How much rent is too much? the 30% rule in practice
Sydney renters in high-demand pockets now routinely spend 35 percent or more of income on housing, testing the long-standing affordability benchmark.
How we reported this
More than one in three Sydney rental households now pay above the 30 percent income threshold for housing costs, according to the latest Domain rental affordability data released this month.
The squeeze has intensified since the start of 2025 as net overseas migration added 180,000 people to New South Wales and inner-ring vacancy rates stayed below 1.5 percent. Households on median incomes of roughly $95,000 face weekly rents that leave little margin once transport, utilities and groceries are covered.
Where the 30 percent line is crossed daily
In Newtown, a two-bedroom terrace on King Street now lists for $820 a week. A single earner on $85,000 clears about $1,250 after tax, so the property alone absorbs 65 percent of take-home pay. Further north, a one-bedroom apartment near Chatswood station on the North Shore commands $650 a week. For a couple each earning $70,000 the combined rent share sits at 32 percent, already past the guideline before other bills arrive.
NSW Fair Trading figures show the median Sydney unit rent reached $620 a week in June 2026, up 9 percent from the same month last year. CoreLogic tracking puts the detached-house median at $780. Both numbers sit well above the level that keeps a median-income household inside the 30 percent band.
Practical steps for households weighing rent versus purchase
Tenants in the Inner West and Northern Beaches can request a rent review through NSW Fair Trading if increases exceed 10 percent in a 12-month period. Buyers checking the same postcodes should model stamp duty, strata levies and potential rate rises on a $1.4 million median dwelling before assuming ownership will be cheaper. Local agents report that properties under $1.1 million in suburbs such as Marrickville and Dee Why still clear within four weeks when priced to current clearance rates of 68 percent.
Households should run the exact 30 percent calculation on their net weekly income before signing any lease or loan application this quarter. Those already above the line can contact a financial counsellor through the NSW Government’s Rent Assist program to map exit options before the next increase notice arrives.
