How much rent is too much? The 30% rule in practice

For decades, financial advisers have preached the 30% rule: spend no more than 30 per cent of your gross income on rent. It's a neat formula, easy to remember, and universally endorsed by mortgage brokers and community services agencies alike. But in Wollongong's 2026 rental market, it's increasingly a fiction.

Consider a typical scenario: a couple working in the CBD or nearby Figtree, earning a combined household income of $140,000. The 30% rule suggests they should spend roughly $3,500 a month on rent. Yet a two-bedroom apartment in the beachside pockets of Thirroul or Fairy Meadow now averages $2,200 to $2,600 monthly. Closer to the Illawarra Showcaves or Wollongong Central, one-bedroom units rent for $1,800–$2,100. For many, 30% has quietly crept to 35%, 38%, even 42%.

The gap between rent and ownership has become a trap. With the NSW median property price hovering near $860,000—and new-build apartments in the CBD renewal zones starting from $480,000—a first-time buyer on a modest income faces an impossible arithmetic. Rent is eating savings that could become a deposit.

Social worker and financial counsellor perspectives, gathered informally through community centres like Wollongong Community Legal Centre near Crown Street, suggest the stress is real. Renters are making trade-offs: sacrificing savings, cutting discretionary spending, or moving further south towards Shellharbour to find cheaper stock. Meanwhile, parents in established suburbs like Keiraville or Coniston are considering whether their children can ever afford to stay local.

The RBA's recent stance on interest rates—holding firm despite mounting household pressure—has inadvertently widened the renter-buyer gap. Higher rates have cooled property prices slightly, but they've also suppressed wage growth and kept mortgage serviceability tight. Renters, meanwhile, have no interest-rate reprieve; landlords simply pass on rising costs.

Some data points the problem. Rental vacancy in greater Wollongong sits below 2%, meaning tenants have little bargaining power. Median rent for a two-bedroom now requires 35%+ of a $100,000 household income. That's no longer a guideline—it's a new norm.

Breaking the 30% rule doesn't mean failure. But it does mean that Wollongong's younger and lower-income workers face a longer, harder slog to ownership than their predecessors. Without intervention—whether through planning reform to boost supply, or targeted first-home buyer assistance—the rule itself may become obsolete, replaced by resignation.
