A house sit of one to three months runs the same way as a two week sit, but four things change at about the four week mark. A quarterly electricity or water bill falls due while you are away. Mail outgrows the letterbox. Your home and contents policy becomes worth a phone call, because the unoccupancy condition inside it is counted in continuous days. And the written agreement needs clauses a fortnight never needs: who may authorise a repair and up to what amount, what happens if either side ends it early, and who refills the dog's medication in week nine. Settle those four before you go and a three month absence is no harder to arrange than a long weekend.
Long service leave is why a lot of Australian absences run past a month
The Fair Work Ombudsman sets out where the entitlement comes from: most long service leave is governed by individual state or territory laws rather than the national system, and depending on which law or instrument applies, an employee may qualify after somewhere between seven and fifteen years of continuous service. How much you have and when you can take it is a question for that law, your award or your agreement, and this is general information rather than employment advice.
The same shape turns up for a sabbatical, a long stay with family overseas, a contract interstate or a lap of the country in a caravan. The dates come from a work entitlement rather than the school calendar, so the trip often falls outside the December to January crush covered in our guide to Australia's seven week summer. Australians travel year round: the Australian Bureau of Statistics recorded 1,150,920 short-term resident departures in June 2026, 4.6% above the same month a year earlier, in Overseas Arrivals and Departures. A May or August sit competes with far fewer listings than one over Christmas.
What actually changes at about the four week mark
| What | Up to about four weeks | One to three months |
|---|---|---|
| Utility bills | Fall due before you go or after you return | A quarterly power or water bill lands mid-sit |
| The letterbox holds it | It overflows, and a full letterbox is visible from the street | |
| Home insurance | Rarely comes into it | The unoccupancy condition is worth confirming in writing |
| Maintenance | Almost nothing breaks | A hot water system, a pump or a leaking tap usually does |
| Pet medication | One script covers the stay | Refills, monthly preventatives and a check-up fall due |
| Garden and pool | A fortnight of watering | A season of growth, and pool chemistry the sitter manages |
| Seasons | One | A sit can start in autumn and finish in winter |
| The agreement | Dates, animals, keys, vet | Plus repair authority, early exit, running costs and mail |
Your home policy counts unoccupancy in continuous days, and a sitter resets the count
A sitter is usually the thing that protects your cover rather than the thing that threatens it, because the clause behind the worry starts counting only once nobody is sleeping in the home. Our guide to home insurance with a house sitter staying sets out what Australian policies say and the questions to put to your insurer.
What a long sit adds is that the arithmetic finally matters, so put the answer in writing and ask one more question while you have them: what happens to your cover if the sitter leaves partway through and the house sits empty for the rest. Moneysmart, run by ASIC, makes the general point that to find what is not included you need to read the product disclosure statement and check for caps, limits and special conditions. Search yours for unoccupied, unoccupancy, and continuous or consecutive days.
Describe the arrangement accurately when you call
A common piece of forum advice is to tell the insurer that friends are staying over. A house sit is not that, and a description that does not match the arrangement is the kind of thing examined closely at claim time. Say plainly that a house sitter will be living in the home and that no rent is paid, and ask for the answer in writing.
Two things arrive while you are away, and both need a decision before you go
Australia Post offers a mail hold for any period from one week to twelve months, and mail redirection for one, three, six or twelve months. Read in August 2026, a personal hold was $30.70 for the first week and $7.20 a week after, and redirection started at $40.50. The third option is the sitter collecting it and stacking it somewhere agreed, which costs nothing and needs one line about anything urgent. Our guide to mail, parcels and deliveries during a sit has the detail. Check separately what expires while you are away: vehicle registration, a licence, a passport.
The bills are the other arrival. No money changes hands for the sit itself, and the usual convention is that the homeowner keeps the utility accounts in their own name and pays them, so the air conditioning through a Townsville February is on your account. Some households agree a contribution to running costs on very long sits, which is a normal conversation to have. The care is in how it is written, because a contribution to bills is one thing and a payment for the sitting is a different arrangement with different consequences, a line our guide to what changes hands in an Australian house sit works through.
Six clauses matter on a long sit that a fortnight never needs
| Clause | What it decides | Why a fortnight never needs it |
|---|---|---|
| Repair authority and a dollar ceiling | Whether the sitter can call a plumber at 9pm, up to what amount, and who first | Over two weeks almost nothing breaks |
| Early end, in both directions | The notice each side gives, and what happens to the animals if it is used | Two week plans rarely change mid-sit |
| Running costs | Who pays the bills that fall due, and in whose name the accounts stay | No quarterly bill lands inside a fortnight |
| Mail and parcels | Hold, redirect or collect, and what the sitter does with anything urgent | A fortnight of mail fits in the letterbox |
| Visitors and overnight guests | Whether the sitter may have someone stay, and for how long | It rarely comes up over two weeks |
| Seasonal work | Mowing across a season, pool chemistry, gutters before fire season | A fortnight has one kind of weather |
Everything else belongs in the standard document. Our house sitting agreement guide has the full clause list and the wording to copy, and the pet care handover template is the page you leave in the house. If the sit spans summer in the southern states, add fire danger days, which our guide to house sitting during bushfire season covers.
Pet care across three months is a diary, not a list
A fortnight of pet care is a set of instructions. Three months is a calendar, and what gets missed is whatever was not due the day you left.
- Medication refills. A script covering four weeks does not cover twelve. Agree which vet, who collects, and how it is paid for. Ring the clinic before you go and ask them to note who may bring the animal in and decide in your absence.
- Monthly preventatives. Flea, tick and worming treatments fall due while you are away, and somebody has to apply them.
- Paralysis ticks on the east coast. The RSPCA Knowledgebase notes the paralysis tick is generally found from north Queensland down to Victoria, year round in the north and generally spring to late autumn further south, and that searching the coat thoroughly once a day is the most essential measure even where a product is used. Over three months that daily search is the sitter's job, so show them how.
- Registration and microchip details. The RSPCA's guidance on arranging care for a cat while you are away asks that council registration, microchip and contact details are current, so you can be reached if an animal is lost.
- Emergency vet authority, with a dollar figure. Over twelve weeks the odds of needing it are higher, and our guide to who authorises and pays an emergency vet bill covers how to write that ceiling.
This is general information, not veterinary advice. Tell your own vet a long sit is happening and ask what your animal needs across it.
For sitters, a long sit is the highest-value booking on the board and the hardest to leave
That is exactly why it deserves more questions before you accept, not fewer.
- Is there transport, and how far is the nearest shop, vet and petrol station?
- What is the internet actually like, if you work from where you sit?
- How long can the animals be left alone in a stretch?
- What happens if you have to leave early for a family emergency, and who is the backup?
- Is there work attached that was not in the listing: a pool, a large garden, livestock, an end of stay clean?
The weeks either side of a long sit decide whether this way of living works, and our guide to house sitting between rentals covers them.
What this article does not cover
Long absences raise a question about what status a live-in sitter has in a home. That is a matter of state and territory residential tenancy law, it is outside what this article covers, and the place to ask is your own solicitor or the relevant office on the ACCC's list of state and territory consumer protection agencies. Nothing here is legal, tax, veterinary or insurance advice.
Common questions about long house sits in Australia
- How long can a house sit last in Australia?
- There is no fixed limit. Sits of one, two and three months are ordinary, and the length is set by the homeowner's absence. What changes past about four weeks is how much has to be agreed in writing beforehand.
- Do you pay a house sitter for a three month sit?
- In a non-monetary exchange, no. The sitter stays free for the agreed dates and cares for the animals and the house, and the accommodation is the whole of what they receive, however long the sit runs. A paid pet sitting booking is a different arrangement using similar words.
- Who pays the electricity bill during a long house sit?
- The usual convention is that the homeowner keeps the utility accounts in their own name and pays them, including a quarterly bill falling due mid-sit. Some households agree a contribution to running costs on very long sits. Either works, provided it is written down before the sit starts.
Post a listing, free
Write the dates, the animals and the honest shape of the sit, including the garden, the pool and whatever else comes with three months rather than three days, so the people who want a long sit can find it. Posting a listing is free for homeowners on Sitterly, no money changes hands for the sit and there is no commission on a booking, and you can see what is open across Australia first. Sitterly supports the connection. Homeowners and sitters remain responsible for their own arrangements.
