Roommate Agreement Australia: What to Include and How to Create One
Moving in with a roommate is exciting — but without a written agreement, small misunderstandings can turn into big problems. A roommate agreement (also called a housemate agreement or share house agreement) puts everyone on the same page from day one.
This guide covers everything you need to know about roommate agreements in Australia — what they are, what to include, whether they're legally binding, and how to sign one online without a lawyer.
What is a Roommate Agreement?
A roommate agreement is a written contract between people sharing a rental property. It covers the practical arrangements that a standard lease with a landlord doesn't address — things like how rent is split, who pays which bills, house rules, and what happens when someone wants to move out.
In Australia, you'll hear it called several things: roommate agreement, housemate agreement, share house agreement, or room rental agreement. They all refer to the same thing — a private contract between the people living together.
A roommate agreement is separate from your lease. Your lease is with the landlord — your roommate agreement is between you and the people you live with. Both can exist at the same time.
Is a Roommate Agreement Legally Binding in Australia?
Yes — a properly written roommate agreement is a legally binding contract under Australian law. For it to be enforceable, it needs the basic elements of a valid contract: an offer, acceptance, and consideration (something of value exchanged, like rent payments).
A signed roommate agreement can be used as evidence in state tenancy tribunals like VCAT (VIC), NCAT (NSW), QCAT (QLD), SAT (WA), and TASCAT (TAS) if a dispute arises.
An unsigned or verbal agreement offers almost no legal protection. If a dispute goes to a tribunal, it becomes one person's word against another's.
What to Include in a Roommate Agreement
A solid roommate agreement should cover all of the following:
1. Rent and Payment Terms
- How much each roommate pays per week or month
- Which day rent is due
- How rent is paid (bank transfer, direct debit, etc.)
- What happens if someone pays late
- Who collects the rent and forwards it to the landlord
2. Bond Contributions
- How much bond each person contributed
- Whose name the bond is lodged in
- Conditions under which bond can be deducted at the end
- Process for settling bond if one roommate leaves early
3. Bills and Utilities
- Which bills are shared (electricity, gas, internet, water)
- How bills are split — equally or by usage
- Who manages each account and whose name it's under
- Deadline for reimbursing the bill-payer each month
4. House Rules
- Quiet hours (especially important in apartments)
- Guest and overnight visitor policy
- Cleaning rosters and shared area standards
- Parking arrangements
- Smoking and vaping policy
- Pets (only if allowed under your main lease)
5. Notice Period and Moving Out
- How much notice a roommate must give before leaving
- Who is responsible for finding a replacement
- What happens to the departing roommate's rent obligations during the notice period
- Whether remaining roommates have the right to approve a new roommate
Most overlooked clause: The notice period. Without one, a roommate could technically leave with no warning, leaving others to cover the full rent. A 28-day written notice is standard in Australian share houses — and worth including even among close friends.
Does a Roommate Agreement Need to Be Signed?
Yes — and both parties need to sign it for it to be enforceable. An unsigned agreement is basically just a document one person wrote. The signature is what makes it a contract.
You don't need to go to a lawyer or notary to sign a roommate agreement. Electronic signatures are legally valid in Australia under the Electronic Transactions Act 1999 (Cth) and equivalent state legislation. You can create and sign a roommate agreement online in minutes using Signed Sorted.
Free Roommate Agreement Template vs. Creating One Online
You'll find free roommate agreement templates online, but most have two problems:
- They're written for US or UK law — not Australian law
- They're generic forms that don't reflect your actual situation
- Getting both roommates to sign a physical document is cumbersome
- There's no secure storage or record of the signed version
A better approach is to use Signed Sorted to create a custom roommate agreement. You describe your situation in plain English — rent amount, bond split, house rules, notice period — and the AI drafts a proper Australian-law agreement. Both roommates can e-sign online from their phones, and a sealed PDF is emailed to everyone instantly.

Create Roommate Agreement →Roommate Agreement vs. Housemate Agreement — Is There a Difference?
In Australia, the terms are used interchangeably. "Housemate agreement" is the more common term locally, while "roommate agreement" is more commonly used in the US. Both refer to the same type of document — a private contract between people sharing a rental property.
What matters is the content of the agreement, not what you call it. Whether you call it a roommate agreement, housemate agreement, or share house agreement, the legal requirements are the same.
Which States Does a Roommate Agreement Cover?
A roommate agreement created through Signed Sorted is valid across all Australian states and territories — VIC, NSW, QLD, WA, SA, TAS, ACT, and NT. The agreement operates under general contract law, which applies Australia-wide. Where state-specific rules apply (such as rental bond laws), the agreement will reference the correct legislation for your state.
Frequently Asked Questions
Can a roommate refuse to sign an agreement?
Yes — you can't legally force someone to sign. But a roommate who refuses to put anything in writing before moving in is a red flag. It's worth having an honest conversation about why they're hesitant before proceeding.
What if one roommate is on the main lease and others aren't?
This is very common. The person on the lease is legally responsible to the landlord. A roommate agreement between all the housemates — including the leaseholder — protects everyone's rights internally, even if only one name appears on the main lease.
Can we change the agreement after signing?
Yes — all parties can agree to amend the agreement at any time. Any changes should be documented in writing and signed by everyone affected. You can create an amended agreement through your Signed Sorted dashboard.
Does the roommate agreement override the main lease?
No. The lease with the landlord always takes precedence. Your roommate agreement governs the relationship between housemates — it cannot override any obligations in the main lease. Make sure your roommate agreement is consistent with your lease (e.g., don't allow pets in the roommate agreement if pets aren't permitted in the lease).
What if a roommate stops paying rent?
A signed roommate agreement gives you the clearest legal basis to pursue the debt — either through negotiation, demand letter, or a state tenancy tribunal. Without a written agreement, enforcement becomes much harder.
