Subletting—renting out your rental property to someone else while you’re still on the lease—seems straightforward until you actually try to do it. Then you discover a web of lease clauses, state regulations, and landlord permissions that make it much more complicated than expected.

Getting subletting wrong can result in lease termination, eviction, and losing your bond. Understanding the actual rules matters if you’re considering having someone else live in your rental temporarily.

What Subletting Actually Is

Subletting means you remain the tenant on the lease, but someone else (the subtenant) lives in the property and pays you rent. You’re still responsible to your landlord for rent and property condition. The subtenant is responsible to you, not directly to the landlord.

This is different from transferring the lease, where you exit entirely and someone else takes over as tenant. It’s also different from getting additional occupants approved, where everyone is on the lease together.

The key characteristic of subletting: you maintain tenancy rights and obligations while someone else occupies the property.

What Your Lease Says

Most standard residential leases include clauses prohibiting subletting without landlord consent. The clause usually says something like “The tenant must not sublet the property or any part of it without written permission from the landlord.”

This means subletting without permission violates your lease. The landlord can issue a breach notice and potentially terminate your tenancy if you sublet without asking.

But the clause says “without permission,” which implies you can request permission. Whether the landlord has to be reasonable in granting or denying permission varies by state.

State Law Differences

In NSW, landlords must not unreasonably withhold consent to subletting. If you request permission and the landlord refuses, they need to have reasonable grounds. “I don’t want to” isn’t reasonable. “The proposed subtenant has poor rental history” might be.

If your landlord unreasonably refuses, you can apply to NCAT. The tribunal will decide whether the refusal was reasonable and can order the landlord to consent to subletting.

In Victoria, similar rules apply—landlords can’t unreasonably refuse consent. But what counts as “reasonable” involves judgment calls that can go either way.

In Queensland, landlords have more discretion. They can refuse subletting for reasons that might not be considered reasonable in NSW or Victoria.

The practical impact: subletting is more viable in states with strong tenant protections and less viable where landlords have more discretion to refuse.

When Landlords Can Refuse

Even in tenant-friendly states, landlords can reasonably refuse subletting in some circumstances:

• The proposed subtenant has poor rental history or credit
• Subletting would increase occupancy beyond what the property can accommodate
• The subtenant intends to use the property for commercial purposes
• The tenant has a poor history with the landlord (late payments, property damage)
• The subletting arrangement is vague or risky for the landlord

Landlords can’t refuse based on discrimination grounds—race, religion, family status, etc. But they have wide latitude to refuse based on risk assessment.

If you’re asking to sublet for legitimate reasons—relocating temporarily for work, extended travel, caring for a family member elsewhere—and you provide a reliable subtenant with good references, refusal is harder to justify.

The Request Process

Requesting permission to sublet should be formal and written. Include:

• Why you need to sublet
• How long the sublet would last
• Information about the proposed subtenant (references, employment, rental history)
• Your commitment to remain responsible for rent and property condition
• How you’ll manage the arrangement (will you be contactable, will you conduct inspections)

The more professional and detailed your request, the harder it is for a landlord to refuse reasonably. If you just say “I want to sublet for a few months,” expect rejection. If you provide a comprehensive plan with a reliable subtenant, you have better odds.

Get the landlord’s permission in writing if they agree. Verbal agreements aren’t enforceable and won’t protect you if problems arise later.

Risks of Subletting Without Permission

If you sublet without permission and your landlord finds out, they can:

• Issue a breach notice requiring you to end the subletting
• Terminate your tenancy if you don’t comply with the breach notice
• Keep your bond for any damage caused by the subtenant
• Sue you for any losses resulting from the unauthorized sublet

The risk isn’t worth it. Even if you think your landlord won’t find out, things go wrong—neighbors complain, the subtenant causes issues, an emergency requires landlord access. When you get caught, you lose your tenancy.

Liability When Subletting

When you sublet legally with permission, you remain the tenant. This means:

• You’re still liable for rent even if your subtenant doesn’t pay you
• You’re liable for any damage the subtenant causes
• You’re responsible for ensuring the subtenant follows lease terms
• The landlord deals with you, not directly with the subtenant

This is risky. If your subtenant stops paying you, you still owe your landlord. If they damage the property, your bond gets claimed. If they violate the lease, you get the breach notice.

You can create a sublease agreement with your subtenant that makes them liable to you, but this doesn’t change your liability to your landlord. You’d need to pursue the subtenant separately to recover costs.

Short-Term Subletting and Airbnb

Using your rental as a short-term rental or Airbnb almost certainly violates your lease unless you have explicit written permission. Most leases prohibit commercial use, and short-term rentals are commercial activities.

Landlords are increasingly alert to tenants running Airbnbs in rental properties. If caught, expect immediate lease termination. The potential income from Airbnb is not worth losing your tenancy and bond.

Some landlords might agree to short-term subletting for specific occasions—you’re away for a month and want someone to stay in your place—but ongoing Airbnb operation will be refused.

Alternatives to Subletting

If you need to be away from your rental temporarily but don’t want subletting complications, consider:

• Getting additional occupants approved who can stay while you’re away
• Negotiating a lease pause or early termination if you’re relocating
• Finding someone to take over the lease entirely if you’re not returning
• Keeping the rental and paying rent while away, if financially viable

These alternatives avoid the legal complexity and liability issues that subletting creates.

When Subletting Makes Sense

Despite the risks and complications, subletting is sometimes the right choice:

• You’re temporarily relocating but plan to return
• Breaking the lease would cost more than continuing to pay rent
• You have a reliable friend or family member who needs temporary housing
• Your landlord is reasonable and willing to grant permission

In these cases, follow proper procedures: get written permission, create a clear sublease agreement, maintain communication with both landlord and subtenant, and stay responsible for all lease obligations.

Subletting can work when done properly. Most problems arise from unauthorized subletting or informal arrangements without clear agreements. Understanding the rules and following proper process makes subletting viable rather than risky.
