Subletting Victoria rental vs Airbnb — two regimes landlords routinely confuse
Subletting Victoria rental property law and short-stay law are different legal regimes with different consent rules, different commercial treatment, and very different financial consequences for the landlord. Conflating the two is the most common mistake we see when an owner calls us in a panic because the upstairs neighbour has flagged a rolling cast of weekend strangers letting themselves into a property the owner believed was on a standard 12-month lease.
Sub-letting under the Residential Tenancies Act 1997. A residential sub-tenancy is the proper, long-term arrangement where the head tenant lets all or part of the property to a sub-tenant — typically another individual who moves in for months or longer. Sub-letting is regulated by the RTA 1997 and, since 29 March 2021, requires the landlord's consent but the landlord must not unreasonably refuse. The arrangement looks and behaves like a residential tenancy throughout.
Short-stay accommodation (Airbnb, Stayz, Booking.com). Short-stay is the renting out of the property — usually the whole property — to paying guests for periods of days or a handful of weeks. It is a different category of use. The Victorian Government and most lease templates treat it as a quasi-commercial activity. From 1 January 2025 it is subject to the Victorian Short-Stay Levy at 7.5% of total booking revenue, separate from GST and land tax. Most modern residential leases (REIV templates since 2021) include a 'no short-stay' clause by default, which makes any unauthorised Airbnb listing an immediate breach.
Why this matters financially to the landlord. A long-term sub-tenant approved through the proper RTA pathway adds zero new risk — the head tenant remains liable, the bond is intact, the insurance is unchanged, and the property is still a residence. An unauthorised short-stay operation, on the other hand, voids the standard landlord insurance policy, exposes the property to owners-corporation enforcement, can trigger council fines, and leaves the landlord with no bond protection against damage caused by the parade of guests. This article walks through both regimes, then the detection and enforcement playbook OptimaRea uses when we suspect a tenant has crossed the line.
Sub-letting under the RTA 1997 — the 2020 reform and what 'unreasonably refuse' means
The sub-tenancy framework was substantially reformed in the 2018-2021 round of changes to the Residential Tenancies Act 1997 (Vic). The reformed rule came into effect on 29 March 2021 and matches the position long applied in commercial leases.
The reformed rule. A tenant has a statutory right to sub-let or assign all or part of their interest in the tenancy with the landlord's consent, which the landlord must not unreasonably refuse. Consent must be in writing. A refusal must state the specific ground. The decision window is 14 days from a complete written request.
What counts as reasonable refusal. The landlord can refuse on any of these grounds, all accepted at VCAT: the proposed sub-tenant fails standard tenant-screening criteria (insufficient income, poor rental history, failed credit check, adverse tenancy-database listing); the proposed occupant numbers would exceed reasonable capacity; the arrangement would breach another law (planning permit, owners-corporation rules, short-stay rules); the proposed sub-tenant has been the subject of a successful VCAT order in a previous tenancy.
What counts as unreasonable refusal. A landlord who refuses on any of these grounds risks a VCAT compensation order: age (over 18); nationality or visa status (with lawful right to reside); family composition, children, or pregnancy; occupation, employment status, or source of income (including Centrelink); religion, race, sexuality, or any attribute protected under the Equal Opportunity Act 2010 (Vic). 'I just don't want strangers in the property' is not a lawful refusal.
What sub-letting does NOT change. The head tenant remains the head tenant. The lease continues. The bond stays with the RTBA against the head tenant's name. The head tenant remains fully liable for rent, damage, and any breach by the sub-tenant. The landlord's contractual relationship is with the head tenant — the sub-tenant is the head tenant's responsibility. This is precisely why most landlords, once they understand the position, are comfortable consenting: the credit risk does not change.

Short-stay is different — REIV lease clauses, planning treatment, and the Short-Stay Levy
Short-stay accommodation — Airbnb, Stayz, Booking.com short-stay listings, and the long tail of smaller platforms — sits in a different legal box from sub-tenancy. The Victorian Government, the major insurers, and most modern residential leases treat short-stay as a separate, quasi-commercial use of a residential property, not as a flavour of residential sub-letting.
The standard lease position. Since the 2021 update, the REIV Residential Tenancies Agreement — the template around 70% of Victorian landlords use — has included an express clause prohibiting short-stay use or listing on any short-stay platform without the landlord's written consent. Many bespoke leases drafted by solicitors go further. Reading the lease is the first step before assuming there is a short-stay problem — in 9 out of 10 properties, the lease already blocks it on its face.
Why the lease draws a line the RTA 1997 itself does not. The RTA governs residential tenancies — situations where the tenant has the property as their home. Short-stay use is the tenant operating the landlord's asset as a short-term accommodation business. A landlord refusing consent under the sub-tenancy reasonableness test would almost certainly be acting reasonably — the use is commercial, the risk profile is different, and the insurance position changes.
The Victorian Short-Stay Levy — 7.5% from 1 January 2025. The Victorian Short-Stay Levy, legislated in 2024 and in force from 1 January 2025, applies a 7.5% levy on total booking revenue from short-stay accommodation in Victoria. The levy is payable by the platform or the host depending on channel, separate from GST and from land tax. A property generating $60,000/year of short-stay revenue produces a $4,500/year levy liability on top of any other tax position. The levy does not apply to a person's principal place of residence — but a tenanted investment property the tenant is sub-letting on Airbnb does not qualify for that exemption.
City of Melbourne short-stay register. Within the City of Melbourne LGA, properties offered as short-stay for 90 or more nights per calendar year must be registered on the City of Melbourne short-stay accommodation register and comply with the register's code of conduct. Other inner-Melbourne councils (Yarra, Port Phillip, Stonnington) have parallel rules. Unauthorised short-stay use can trigger council compliance action independent of any landlord-tenant dispute.
Owners-corporation bans, insurance exclusions, and the bond gap
The financial exposure on an unauthorised short-stay operation goes well beyond the levy. Three structural issues sit underneath every Airbnb-on-a-rental scenario and each is a real cost to the landlord.
Owners-corporation bans. Around 60-70% of Melbourne OC-managed apartment buildings now have rules expressly prohibiting short-stay use. These rules are registered against the title and enforceable against the lot owner — not the tenant. If the tenant runs an unauthorised Airbnb, the OC's enforcement target is the landlord. Standard OC enforcement runs through breach notices, fines, and ultimately a VCAT application against the lot owner. The landlord recovers from the tenant under the lease — slow and uncertain. For OC-governed properties, the OC ban is almost always the binding constraint.
Landlord insurance exclusions. Every major landlord-insurance product in Victoria (Terri Scheer, EBM RentCover, NRMA, Allianz, Suncorp) excludes short-stay use. Some insurers offer a short-stay endorsement at a 50-100% premium loading, but the standard product does not cover damage, theft, or liability arising from short-stay guests. If a guest causes $20,000 of damage, the claim is declined the moment the assessor sees the booking history. See OptimaRea's landlord insurance guide.
The bond gap. The bond covers damage by the tenant. It does not cover damage by short-stay guests — guests are not parties to the tenancy. A four-week bond on a $700/week property is $2,800, wholly inadequate for the damage a single bad weekend of short-stay can produce. The landlord's protection is the tenant's contractual liability, not the bond.
Stacking the three. A tenant running an unauthorised Airbnb in an OC-banned apartment with a $20,000 damage event creates: an OC fine and breach action against the landlord, an insurance claim declined for short-stay exclusion, a bond of $2,800 against $20,000 of damage, plus the levy liability the host failed to register. The total downside on a single bad-tenant scenario can easily exceed the gross rent for the entire year. This is why detection and enforcement matter more on short-stay than on almost any other lease-breach category.
Detection — the markers OptimaRea inspectors look for
Across the OptimaRea management book, we see signs of unauthorised short-stay use in roughly 2-3% of inspected properties — low base rate, but the financial impact per case is severe enough that we run an explicit short-stay-detection checklist on every routine inspection in suburbs and apartment buildings where the base rate is higher (Melbourne CBD, Docklands, Southbank, St Kilda, Carlton, Brunswick, Fitzroy).
Physical markers visible at inspection. Rotating cleaning supplies (stacks of fresh microfibre cloths, multiple unopened soap and shampoo bottles, unusually large toilet-paper supply — turnover-schedule quantities rather than household use); a lock box near the front door, gas meter, or fence (the classic Airbnb key-handover device); multiple identical sets of keys laid out (3-4 sets is excessive for a 2-3 person household); commercial-grade or hotel-style linen; a printed 'welcome' or 'house rules' document on the bench; QR codes on the wall pointing to wi-fi or check-in info; sealed individual coffee pods or UHT milks uncharacteristic of a residential household.
Building and neighbourhood markers. Neighbour complaints about parties, noise, or strangers coming and going at odd hours; the OC manager flagging unusual visitor traffic or repeated reception questions; guest-style rubbish patterns; parcels arriving for names that don't match the tenant.
Online listing search. Every quarter we run a suburb-and-address search across Airbnb, Stayz, Booking.com short-stay listings, and the long-tail platforms (Vrbo, HomeAway). Listing photos often show distinguishing features (a particular splashback, a balcony view) and a careful operator recognises their own apartment in another tenant's listing within seconds.
Council and OC information. For City of Melbourne properties offered for 90+ nights, the register is public — we cross-check it against our managed properties annually. The OC's records of incidents, breach notices, and complaints are accessible to the lot owner and we draw on these when we suspect a problem.
The escalation path when markers are present. Photograph the markers during routine inspection (the inspection is lawful under the standard notice), document complaint patterns, run the online listing search, and report to the landlord in writing with the evidence stack before any direct conversation with the tenant. A premature conversation tips off the tenant, who closes the listing for a fortnight and reopens under a different name once the heat is off.
Enforcement — Notice to Vacate, VCAT, and the breach pathway
When the evidence is clear that the tenant is running an unauthorised short-stay operation, the enforcement pathway runs through the standard breach-of-lease and Notice to Vacate process under the RTA 1997. There is no Airbnb-specific provision, but the existing toolkit is more than adequate.
Step 1 — Breach of duty notice. The first formal step is a Breach of Duty Notice under section 208 of the RTA 1997, citing the specific lease clause prohibiting short-stay use and the specific breach (Airbnb listing for the property's address, lock box, neighbour complaints). The notice gives 14 days to remedy and warns that further breach will be grounds for termination.
Step 2 — Notice to Vacate for breach of lease. If the breach continues or recurs within 6 months of the breach notice, a Notice to Vacate can be served under section 91ZG (the general breach pathway) with a 14-day vacate period. For repeated or serious breaches, the 14-day notice is enforceable at VCAT for a possession order. For the broader notice and termination framework see OptimaRea's rental property management Melbourne overview.
Step 3 — VCAT application for possession + compensation. If the tenant doesn't vacate by the notice date, the landlord applies to the VCAT Residential Tenancies List for a possession order plus a compensation order for damages attributable to the unauthorised use (cleaning, repairs, OC fines, insurance shortfall), any rent owing, and legal costs in some scenarios. The compensation order is enforceable as a judgment debt.
The evidentiary standard. VCAT operates on the balance of probabilities. The standard evidence stack is inspection-report photos of the markers, the online listing printout, neighbour or OC complaint records, and the breach notice with proof of service. Tenants who fight at VCAT typically concede on the substantive breach and argue only on the remedies.
The settlement pattern. Around 70-80% of cases resolve at the breach-of-duty notice stage — the listing comes down, OC complaints stop, the lease continues. 15-20% require the Notice to Vacate and the tenant leaves voluntarily before the VCAT hearing. The residual 5-10% run to a hearing, and the landlord wins the possession order in essentially all of those where the evidence stack is complete.
When the tenant asks for permission — saying yes, saying no, conditional consent
Some tenants will ask. A request to list the property on Airbnb arrives by email or via the property manager and the landlord has to decide whether to consent, refuse, or consent on conditions.
The default position — refuse. Our recommended default is to refuse. The reasons stack in one direction: insurance excludes short-stay use, most OCs prohibit it, the bond is structurally inadequate, the lease clause is on the landlord's side, and the 7.5% Short-Stay Levy plus registration obligations create administrative complexity the landlord doesn't want to own. Refusal is reasonable under any objective standard — short-stay is a commercial use and the landlord is entitled to insist the property be used as a residence.
The exception cases. Two narrow scenarios. First, the tenant proposes a small number of nights per year (10-20 nights while on holiday) and the property has no OC short-stay ban — the levy exposure is small, the insurance gap is short. Second, the landlord is actively considering converting the property to dedicated short-stay management and the tenant's request is a low-risk pilot. Neither is common.
Conditional consent — the structure. If consent is given, it must be written and conditional on: a hard cap on nights per year (below the 90-night City of Melbourne register threshold unless registration is intended); the tenant's written acknowledgement of responsibility for the Short-Stay Levy and any council registration; written acknowledgement that landlord insurance does not cover short-stay and any guest-caused damage is the tenant's full liability under the lease; confirmation that OC rules permit short-stay (with the rules attached); an inspection clause allowing inspection during a guest stay on 24 hours' notice; immediate-termination clause if any condition is breached.
The 'sub-letting workaround' some tenants attempt. A handful of tenants try to dress up a short-stay operation as a 'long-term sub-tenancy' to access the sub-tenancy reasonableness test — typically a series of overlapping 30-60 day 'sub-tenancies' to different individuals who never move in. This is a sham and VCAT treats it as such. The substance-over-form test asks whether the occupant is genuinely using the property as their residence — a rolling cast of weekend stays plainly is not.
The OptimaRea practical view — managing the short-stay risk on every property
Across our managed book we run a low-overhead short-stay-risk protocol on every property in suburbs and buildings where the base rate of unauthorised short-stay attempts is material.
Lease drafting. Every lease we draft for an owner client includes an explicit no-short-stay clause that goes beyond the REIV template — expressly prohibiting listing on Airbnb, Stayz, Booking.com, Vrbo or any equivalent platform; prohibiting any payment for short-stay occupancy; and characterising breach as serious-breach grounding immediate Notice to Vacate. This closes off the argument that the lease only contemplated traditional sub-letting.
Routine inspection protocol. Our inspectors are trained on the marker checklist above and run it on every routine inspection. Two minutes per inspection. The catch rate is roughly one unauthorised operation flagged per 30-40 inspections in high-base-rate suburbs. Markers are photographed (under the standard inspection notice) and reported to the landlord in writing within 24 hours, before any direct conversation with the tenant.
Quarterly online listing search. Every quarter we run a suburb-and-address search across Airbnb, Stayz, and Booking.com listings, cross-checking photos against properties we manage. Around 30 minutes per 100 properties, catching roughly one additional operation per quarter the inspection didn't surface.
On a confirmed short-stay breach. Straight to the breach-of-duty notice with the evidence stack. 70-80% resolve at this stage; 20-30% run to Notice to Vacate; a small minority require a VCAT hearing.
On a tenant who asks for permission. We brief the landlord on the financial framework (levy, insurance gap, OC position, bond gap), recommend default refusal in nearly all cases, and draft a refusal letter on lawful grounds. Where the landlord wants to consent on conditions, we draft the one-page conditional consent letter.
Fee tier. All of the above sits inside OptimaRea's standard property management at 4.90% + GST. Short-stay detection and enforcement is part of standard management, not a paid add-on.
