The Sydney suburbs bracing for population boom as reforms reshape housing map

Sydney’s inner west and middle-ring suburbs are facing the biggest wave of high-density housing development in decades as new figures reveal established communities are set to absorb thousands of apartments under the NSW government’s fast-tracked planning overhaul.

An analysis of major residential projects declared by the Housing Delivery Authority (HDA) shows councils including Canada Bay, Burwood, Ryde, Parramatta, Lane Cove and North Sydney have become the focal point of a development surge aimed at tackling the state’s worsening housing shortage.

The figures underscore a shift away from decades of expansion on Sydney’s outer fringes as developers increasingly use the HDA to target established suburbs where stronger apartment prices have made large-scale projects more viable in an environment of rising land values and prohibitive construction costs.

Established in late 2024, the HDA was designed to accelerate housing construction by allowing projects valued at more than $60 million to bypass council approval pathways and instead be assessed as state-significant developments.

A Herald analysis of HDA-declared projects compared with existing population levels shows Canada Bay is expected to experience the largest proportional increase in high-density housing of any local government area in NSW.

The council region, stretching from Drummoyne to Rhodes, has 7129 dwellings proposed through HDA-declared developments. Relative to its population of 93,006 residents, that equates to almost 77 new homes for every 1000 people.

Burwood ranks second, with 2791 proposed dwellings, or more than 63 homes per 1000 residents, despite the compact seven-square-kilometre council area already undergoing extensive apartment construction over the past decade.

Willoughby, Ryde, Parramatta, Lane Cove, North Sydney and The Hills are also expected to absorb significant increases in residential density, with many developments concentrated around existing and future Sydney Metro stations.

By contrast, western Sydney council areas that have traditionally accommodated much of the city’s population growth have recorded relatively little activity through the HDA pathway.

Campbelltown has fewer than one proposed dwelling per 1000 residents, while Fairfield sits at 3.4 and Penrith at 3.5.

Western Sydney University chief economist Professor Neil Perry said the geographic concentration of projects reflected the economic realities facing the development sector.

“The HDA creates opportunities in areas where higher-density development is financially attractive, and that helps expla
