For four weeks in March 2026, four MELBZ writers (Marcus, Tom, Dani, Mia — me, plus three others) ran a real-receipt diary. Every Coles dock, every Myki tap, every $4.20 chai latte, every $187 Optus mobile bill. No rounded numbers. We chose four households deliberately spread across the metropolitan ladder: my Pascoe Vale family of four, Tom’s Mickleham retired-couple-rental observation, Dani’s Hampton Park family of four (one in childcare), and Mia’s Sandringham couple. Below is the week-of-March-15 snapshot, all four side-by-side.
What it actually costs (2026)
The four households, after-tax weekly spend, March 15-21 2026:
Marcus — Pascoe Vale, family of 4, two school-age kids, two adults, two cars:
- Mortgage repayment: $720/week (was $560 in 2022; rate cycle has done its damage)
- Groceries (Coles + ALDI mix): $278 (ABS Vic average is $212/wk; we run high because two teens)
- Utilities (gas + power + water + 3 mobiles + NBN): $145
- Transport (fuel + rego split + tolls + parking): $215 (AAA 2025 puts car-owner Melbourne household transport at $535/week — we’re under because no commute toll)
- Eating out + coffee: $130
- Kids (sport rego, after-school class, school excursion): $95
- Insurance (home + car + health): $172
- Discretionary (clothes, household, gifts): $145
- Week total: $1,900, annualised $98,800
Tom — Mickleham, couple early-60s, no kids at home, renting a 3BR:
- Rent: $510/week (3BR outer-north house, REIV Q4 2025 data line for Mickleham)
- Groceries: $185 (couple, ALDI heavy)
- Utilities: $115 (lower household, electric heating only)
- Transport: $290 (one car, weekly fuel + monthly rego split + Tom drives Melbourne suburbs for work)
- Eating out: $80
- Insurance + health: $260 (couple over-60 health premium is the kicker)
- Discretionary: $115
- Week total: $1,555, annualised $80,860
Dani — Hampton Park, family of 4, one toddler in 3-day childcare, two adults, one car:
- Mortgage: $680/week
- Groceries: $235 (4-person, ALDI + Coles + Hampton Park Friday markets)
- Utilities: $135
- Transport: $145 (one car + Myki for school kid + occasional second-car-from-rental)
- Childcare (3 days, after CCS subsidy at 76%): $192/week net (full fee was $135/day x 3 = $405; CCS pays 76% of CCS rate cap of $13.73/hr → out-of-pocket settles at around $192/wk for a Hampton Park centre)
- Eating out + coffee: $75
- Kids extracurricular: $60
- Insurance + health: $160
- Discretionary: $95
- Week total: $1,777, annualised $92,400
Mia — Sandringham, couple late-30s, no kids, renting a 2BR unit:
- Rent: $620/week (Sandringham 2BR median, Domain Q1 2026 area data)
- Groceries: $175 (two adults, mostly Coles, weekend Sandringham fishmonger)
- Utilities: $128
- Transport: $215 (Mia commutes Sandringham-CBD on the Frankston line; partner has a car)
- Eating out + brunch + bayside cafes: $245 (the big one — bayside lifestyle line is real)
- Insurance + health: $145
- Discretionary: $190
- Week total: $1,718, annualised $89,340
Where to save (and where it isn’t worth it)
Lines that moved meaningfully across our four diaries:
- Housing — gap from Tom’s $510/wk rent to Mia’s $620/wk rent is $5,720/year for the same number of bedrooms. Suburb is the lever.
- Eating out — Mia ran $245/wk, Dani ran $75/wk. That’s $8,840/year of bayside-cafe-life premium that Hampton Park doesn’t see.
- Childcare — Dani’s $192/wk net is one of the cleanest sub-$200 outcomes we logged because Hampton Park sits in the lower CCS-subsidy band. Inner-suburb centres run $250-$310/wk net for the same 3 days.
Lines that didn’t move much:
- Utilities — across all four households, $115-$145/week. The “switch energy retailers” advice saves $5-8/week, not $30.
- Insurance — health is the only line where life-stage moves it (Tom & wife’s couple-over-60 premium of $260 is the outlier; everyone else was $145-$172).
Per-suburb breakdown
Same family-of-4 household (Marcus’s structure: 2 adults, 2 kids, 2 cars, 3BR house), normalised to 2026 medians:
| Suburb | Housing/wk | Groc/wk | Tx/wk | Other/wk | Total/wk |
|---|---|---|---|---|---|
| Pascoe Vale | $720 (mortgage) | $278 | $215 | $687 | $1,900 |
| Brunswick | $760 | $290 | $185 | $700 | $1,935 |
| Reservoir | $640 | $270 | $245 | $660 | $1,815 |
| Sunshine | $590 | $260 | $245 | $640 | $1,735 |
The Sunshine vs Brunswick gap is $200/week, $10,400/year. Same-sized house, same family. That’s the rent-trade math, made real.
Bottom line
A real Melbourne family of four runs $1,735-$1,935/week in 2026 depending on suburb — that’s $90,000-$101,000/year after tax. A childless couple runs $1,555-$1,720. The single biggest controllable line for both is housing location, not lifestyle. If you’re trying to land under these numbers, look at the suburb shift first; the coffee budget can wait.
