Housemate Agreement Australia: What You Need to Know
Moving into a share house is exciting — but money disputes and misunderstandings about house rules can turn a good situation sour fast. A housemate agreement is the simplest way to protect everyone involved, and it takes less than 10 minutes to set one up properly.
This guide covers everything you need to know about housemate agreements in Australia — what they are, what to include, whether they're legally binding, and how to create one without a lawyer.
What is a Housemate Agreement?
A housemate agreement (also called a share house agreement or room rental agreement) is a written contract between people sharing a property. It sets out the rules everyone has agreed to — covering rent, bills, cleaning, guests, and what happens if someone wants to leave.
It's different from a formal lease agreement with a landlord. A housemate agreement sits between the housemates themselves, covering the practical arrangements that a standard lease doesn't address.
A housemate agreement doesn't replace a lease — it works alongside it. Your lease with the landlord is a separate document. The housemate agreement governs how you and your housemates share the property between yourselves.
Is a Housemate Agreement Legally Binding in Australia?
Yes — a written housemate agreement is a legally binding contract under Australian law, provided it meets the basic requirements of a valid contract: offer, acceptance, consideration (something of value exchanged, such as rent), and intention to create legal relations.
A properly drafted housemate agreement can be used as evidence in a dispute, including in VCAT (Victoria), NCAT (NSW), QCAT (Queensland), or equivalent state tribunals if things go wrong.
An informal verbal agreement offers much weaker protection — if a dispute arises, it becomes one person's word against another's.
What to Include in a Housemate Agreement
A solid housemate agreement should cover the following:
Rent and Payment
- How much each person pays per week or month
- Which day rent is due
- How rent is paid (bank transfer, cash, etc.)
- What happens if someone pays late
Bond
- How much bond each person contributed
- Whose name the bond is lodged under
- Conditions for bond deductions at the end of the tenancy
Bills and Utilities
- Which bills are shared (electricity, gas, internet, water)
- How bills are split — equally, or by usage
- Who is responsible for setting up and managing each account
House Rules
- Quiet hours
- Guest and overnight visitor policy
- Pets (if allowed under the main lease)
- Smoking policy
- Cleaning responsibilities and common area standards
Notice Period and Moving Out
- How much notice a housemate must give before moving out
- Process for finding a replacement housemate
- What happens to rent obligations during the notice period
Pro tip: The notice period clause is one of the most important. Without it, a housemate could leave with one week's notice and leave everyone else scrambling to cover rent. A 28-day notice period is standard in most Australian share houses.
Do You Need a Lawyer to Write a Housemate Agreement?
No. For a standard share house arrangement between private individuals, you don't need a lawyer. A well-drafted template agreement that covers the key terms above is sufficient for most situations.
A lawyer is worth considering if you're dealing with a high-value property, complex financial arrangements, or a situation where one person owns the property and is renting rooms to others (which can create landlord-tenant obligations).
What Happens if There's No Agreement?
Without a written agreement, resolving disputes becomes much harder. Common problems in share houses without agreements include:
- Disputes over who owes what for bills
- One person refusing to leave without adequate notice
- Disagreements about bond deductions
- No agreed process for bringing in a new housemate
State tribunals like VCAT and NCAT can help resolve disputes, but without a written agreement they have little to work with. A written agreement gives the tribunal clear terms to reference.
Which Australian States and Territories Are Covered?
A housemate agreement is valid across all Australian states and territories — VIC, NSW, QLD, WA, SA, TAS, ACT, and NT. The agreement operates as a private contract between the housemates, governed by general contract law principles that apply Australia-wide.
Where state-specific rules apply — such as rental laws in Victoria or NSW that affect how bonds are handled — your agreement should reflect the rules of the relevant state.

Can a housemate agreement override the main lease?
No. The main lease between the tenants and the landlord takes precedence. Your housemate agreement governs the relationship between housemates — it cannot override obligations in the lease.
What if a housemate refuses to sign?
If a housemate refuses to sign an agreement, that's a red flag worth taking seriously before they move in. An unwillingness to commit to agreed terms in writing often signals future problems.
Can we update the agreement after signing?
Yes — both parties can agree to amend the agreement at any time. Any changes should be documented in writing and signed by all parties.
Does the agreement cover the landlord's rules too?
Not directly — but your housemate agreement should be consistent with your main lease. For example, if pets aren't allowed under your lease, your housemate agreement shouldn't permit them.
