Overseas migration is driving Sydney’s record population growth with the city absorbing more than 100,000 new residents every year.
Some of Sydney’s most crowded postcodes now have densities higher than parts of New York City – and the outer suburbs are catching up.
For example, northwest suburb Kellyville Ridge was once a quiet, spacious area. Now those who moved to the suburb for space find themselves in the thick of it with density up almost 700 per cent since 2001.
“There’s a lot more people coming in, traffic is becoming a lot more horrendous than it use to be,” one worried resident told 7News.
“I could see the main road from my house but it’s all roofs now,” another said.
Inner-city spots are among Sydney’s most crowded, but the outer suburbs are absorbing the population growth.
“Housing affordability is driving much of this and people are looking for apartment living because it’s cheaper than homes,” demographer Mark McCrindle said.
“The further out you go, the lower the cost of those apartments.”
Kingsford, Lakemba and Wiley Park now have more people per square kilometre than The Rocks’ 7212 inhabitants.
Other alarming areas include Concord West, whose population increased by 139 per cent between 2001 and 2017, and Homebush, whose shot up 142 per cent for the same period.
Sydney’s densest area has been identified as Potts Point and in neighbouring suburb Woolloomooloo, with over 16,000 people per square kilometre.
Those gargantuan figures are so high they rival parts of New York City.
“The density of Potts Point and Woolloomooloo is above that of Brooklyn,” Mr McCrindle revealed.
“We’ve got among the highest density of any developed cities on the planet.”
The next suburbs predicted to boom are Narellan, Camden and Badgerys Creek.
“Now we’re getting those green fields be turned to apartments – almost overnight,” Mr McCrindle added.
