Sydenham to Bankstown Corridor Rezoning Could Redraw Sydney's Inner-South Property Map

NSW Planning has put a rezoning proposal on the table that would fundamentally alter the built form of suburbs stretching from Sydenham through Marrickville, Dulwich Hill, Hurlstone Park and Campsie to Bankstown, a corridor that until recently has been dominated by single-storey brick bungalows and low-rise retail strips. The proposal, part of the state government's broader Transport Oriented Development program, would allow residential towers of up to 24 storeys within 400 metres of station precincts and mid-rise buildings of six to eight storeys in the wider catchment zone.

The timing is deliberate. Sydney's housing supply crisis has sharpened through 2025 and into 2026, with the NSW median dwelling price sitting around $1.4 million and inner-ring stock at historically tight levels. The Sydenham to Bankstown corridor sits on the new Metro City & Southwest line, which opened the Bankstown branch in late 2024, giving NSW Planning the transport infrastructure argument it needs to justify significant density increases along the route.

What the Uplift Actually Means on the Ground

Walk down Illawarra Road in Marrickville today and the mismatch is obvious: a metro station pumping commuters into streets flanked by R2 low-density zoning. Under the proposed changes, land within a 400-metre radius of Marrickville Metro station could be rezoned to allow residential flat buildings and commercial mixed-use towers that are currently prohibited. The same logic applies at Dulwich Hill station, where Canterbury Road's tired retail strip would become a priority development corridor, and at Campsie, where Canterbury-Bankstown Council has already flagged its own Local Environmental Plan amendments to complement the state overlay.

Canterbury-Bankstown Council is the key local authority involved. Its 2024 Housing Strategy projected that Campsie town centre alone could absorb more than 8,000 new dwellings over 20 years if planning controls permitted it. The rezoning proposal, if gazetted, would give that ambition legal force. Council's draft Local Strategic Planning Statement has already nominated the Campsie and Bankstown CBDs as 'Greater Sydney Strategic Centres,' a classification that fast-tracks rezoning decisions through the Department of Planning.

Developers have been banking land along the corridor since metro construction began. Off-the-plan apartment prices in Campsie were averaging around $850,000 to $950,000 for a two-bedroom unit through the first half of 2026, according to listings tracked on major portals, a significant discount to equivalent product in Marrickville or Newtown, where comparable apartments regularly clear $1.1 million to $1.3 million. That gap is exactly why investor appetite along the Bankstown line remains strong even as parts of Melbourne's market, as reported this week, are recording their worst winter auction results on record.

Residents, Heritage and the Sticking Points Ahead

The proposal is not without friction. Dulwich Hill's conservation area, which covers significant portions of the suburb's Federation and Californian bungalow streetscapes around Ewart Street and Wardell Road, is explicitly carved out of the highest-density uplift zone. Local heritage advocates have been vocal through earlier consultation rounds, and the NSW Heritage Council is expected to lodge a formal submission before the public exhibition closes. The Inner West Council, which covers Marrickville and Dulwich Hill, has previously pushed back on aspects of the state's housing targets, arguing that infrastructure, specifically stormwater, schools and parklands, hasn't kept pace with projected population growth.

The exhibition period for the rezoning proposals closes on August 29, 2026. Any landowner, resident or business operator along the corridor can lodge a submission through the NSW Planning Portal. If the state proceeds without significant amendments, gazettal is expected in early 2027, at which point existing low-density zoning protections fall away and development applications under the new controls can proceed.

For anyone holding property within 600 metres of a metro station between Sydenham and Bankstown, the practical advice is simple: get a valuation now, before rezoning speculation fully prices into the market, and review your existing council zoning certificate against what the proposed controls would permit. The window between exhibition and gazettal is historically when site values move most sharply, and this corridor, priced well below the Inner West median, has room to run.
