Should housemates with bigger rooms pay more rent?

Yes, in most cases. If one room is noticeably bigger or has better features like an ensuite or built-in wardrobe, it's fair for that person to pay more. Measure the rooms, agree on percentages, and write it down. Most share houses in Australia do it this way and it prevents months of quiet resentment.

How much extra should a couple pay for sharing a room?

A common rule of thumb is 1.3 to 1.5 times a single person's share. They're using more water, electricity, and shared spaces, but they're only taking one bedroom. Work it out with your housemates before the couple moves in, not after the first utility bill arrives.

Should bond be split the same way as rent?

Ideally, yes. If you're paying 35% of the rent, you should put up 35% of the bond. It keeps things proportional and makes the maths cleaner when someone moves out and needs their bond back. Get it in writing.

What happens to rent when a housemate moves out?

The remaining housemates cover the gap until a replacement is found. The person leaving should give proper notice and help find someone new. Don't just absorb the extra cost quietly — have a plan in your house agreement for exactly this situation.

Is it legal to charge different rent for different rooms in Australia?

Yes. As long as everyone agrees to their individual amount and it's documented, you can charge different rent for different rooms. In fact, it's standard practice in Australian share houses. Just make sure the total adds up to what's owed to the landlord.

How do you split rent fairly when one room has an ensuite?

The ensuite room typically pays a premium of $20 to $50 more per week, depending on the city and total rent. Some houses bake it into the room-size calculation, others add a flat surcharge. Either way, agree on it before anyone moves in and save yourself the bathroom argument.

How to Split Rent With Your Housemates

Rent is the big one. It's probably eating half your income and it's the first thing that needs sorting when you move into a share house. The tricky bit? Bedrooms are almost never the same size, so splitting it evenly can feel pretty unfair pretty fast.

How to Split Rent Fairly

1

Measure every bedroom

Get out the tape measure and work out the floor space of each bedroom in square metres. Include any extras like an ensuite, built-in wardrobe, or balcony access. This is your baseline for a fair split, and it takes the emotion out of it.
2

Agree on room values

Factor in more than just size. Natural light, street noise, proximity to the bathroom, and whether there's a door that actually locks all matter. Sit down together and agree on what each room is worth as a percentage of total rent before anyone picks a room.
3

Handle couples sharing a room

If two people share one bedroom, they typically pay more than a single person but less than two individual rooms. A common approach is 1.3 to 1.5 times a single person's share. Sort this out on day one, not three months in when resentment's already set in.
4

Set up rent payments

Decide whether everyone pays the landlord directly or one person collects and transfers. Direct payments are cleaner but some landlords prefer a single transfer. Either way, set up automatic payments so nobody's chasing anyone on rent day.
5

Record the agreement

Write down each person's rent amount and keep it somewhere everyone can see. Add it to Split so there's a record. When a new housemate moves in, you've got the split documented instead of trying to remember what you agreed on six months ago.

Ways to Split Rent

Method	How It Works	Best For	Fairness
Equal split	Total rent divided equally between all housemates, regardless of room size.	Houses where all bedrooms are roughly the same size and have similar features.	Medium
Room-size proportional	Measure each bedroom in square metres and split rent proportionally. A room that's 30% of total bedroom space pays 30% of rent.	Most share houses, where bedrooms vary in size. This is the most common and least argued-about method.	High
Income-based	Each housemate pays a percentage of rent that reflects their income relative to the group total.	Houses with a big income gap, like a full-time professional sharing with students.	High
Room auction	Each housemate privately bids what they'd pay for each room. Highest bidder gets first pick, and the remaining rent is distributed among the other rooms.	New share houses where nobody's moved in yet and you want a market-driven approach that everyone buys into.	High

Tips for Splitting Rent

Sort rooms before moving in

Negotiate rent splits before anyone claims a room. Once someone's unpacked, they're not going to agree to pay more. Do the awkward chat while everyone's still standing in an empty house.

Factor in the bond

Bond should match the rent split, not be equal across the board. If you're paying 40% of rent, you should put up 40% of the bond. It's fairer and avoids drama when someone moves out.

Review when housemates change

When someone moves out and a new person arrives, it's a natural moment to revisit the split. The new housemate shouldn't just inherit the old deal without agreeing to it.

Document everything for the lease

If everyone's on the lease, make sure each person's individual rent amount is written down somewhere all housemates can access. If only one person is on the lease, the others need a subletting agreement.

Couples should talk it through

If you're moving in as a couple, discuss with your housemates what's fair before signing anything. Don't assume two people in one room pay exactly double — but don't assume single-room rate either.
