The Leak List

One household. One page. Where the money is already going out, and the exact swaps that stop it. No budget. No willpower. Every number sourced.

Worked example — a family of four, renting a 3-bed

Rent is fixed. This is about everything around it. You don't need to earn more or try harder. You need to find the leaks.

#	The leak	The swap	Saves
1	Second fridge or freezer running in the garage	Turn it off. One fridge is enough.	$85–250/yr
2	Old showerhead, no star rating	Swap to a 4-star (WELS). Two-minute job.	~$315/yr water
3	Dryer for every load	Line or rack; dryer only when it rains	~$85/yr
4	Draughts under doors, around windows, unused vents	Seals and a door snake	up to 25% of heating/cooling
5	Thermostat set once and forgotten	1–2°C lower in winter, higher in summer	5–10% per degree
6	Half the lights still halogen or incandescent	Swap to LED as each one dies	lighting is ~10% of the bill; LEDs cut ~75% of it
7	Hot water cylinder set high	Drop to 60°C. It's also the safe minimum.	hot water is 15–27% of home energy
8	Standby everything — TVs, consoles, chargers	Switch off at the wall overnight	small, but it compounds

First-year, realistic: roughly $600–900.

None of these need a budget, a spreadsheet, or discipline. Four of the eight take under five minutes. Two cost nothing. Figures from the Australian Government household energy guide (energy.gov.au), read 28 Sep 2026.

What this is not

Not financial advice. Not a budget. Not "try harder." I don't ask anyone to track spending or give up anything they want. I read a house the way I read a supply line: find where it's leaking, stop the leak, leave the rest alone.
