There are now more than 300 Sydney suburbs where it is typical for home loan repayments to top $30,000 annually, according to census data provided to Fairfax Media by the Australian Bureau of Statistics (ABS).

The median mortgage repayment identifies the middle repayment of all home loan borrowers in a given suburb; that is, half of the repayments in that suburb were higher than the median value and half were lower than the median value.

Dawes Point, which is adjacent to the southern pylons of the Harbour Bridge, currently has Sydney’s highest annual median mortgage repayment at $62,400.

Six more harbour-side and northern beaches suburbs have median annual home loan repayments of more than $50,000 annually. These are Duffys Forest ($60,000), Whale Beach ($57,200), Clontarf ($52,000), Linley Point ($52,000), Longueville ($52,000), and Balgowlah Heights ($51,500).

Another 34 Sydney suburbs have a median mortgage bill of more than $40,000 annually, while 309 suburbs have a median home mortgage repayment of $30,000 annually or more.

The lowest median mortgage repayment in the Greater Sydney region is at Patonga on the Central Coast, at $7,550 per year. Some suburbs in south-western Sydney also have relatively low median repayments, including Airds near Campbelltown ($14,400 annually), Carramar near Fairfield ($16,000) and Miller near Liverpool ($17,400).

Across Greater Sydney, the median mortgage repayment is $26,004 annually according to the 2016 census. This was nearly $5,000 a year higher than the national median mortgage repayment.
