Sydenham to Bankstown Corridor Rezoning Could Reshape One of Sydney's Last Affordable Belts

NSW Planning has placed a rezoning proposal on public exhibition that would fundamentally alter the low-rise character of suburbs stretching from Marrickville in the inner west to Bankstown in the city's south-west, a corridor long coveted by developers but fiercely protected by local councils reluctant to trade fibro cottages for apartment towers.

The proposal, lodged under the Transport Oriented Development program, targets station precincts at Sydenham, Marrickville, Dulwich Hill, Hurlstone Park, Canterbury, Campsie and Bankstown. Under the draft controls, land within 400 metres of each station platform could be rezoned to permit residential flat buildings of up to 10 storeys, replacing existing height limits that in some pockets still cap construction at two storeys.

Why This Corridor, Why Now

The timing is not accidental. The state government's Housing and Productivity Contribution, introduced in mid-2023, imposed a levy on new developments but was bundled with commitments to fast-track supply in rail-accessible suburbs. The Sydenham-to-Bankstown segment of the Metro Southwest line, now operating as the Sydney Metro City and Southwest, gives the corridor genuine transit credentials that planners argue justify increased density.

Canterbury-Bankstown Local Government Area already recorded one of the highest population growth rates in Greater Sydney over the past five years, driven by migration from Lebanon, Vietnam and more recently South and Southeast Asia. Campsie's Beamish Street and Bankstown's North Terrace are among the most commercially active strips outside the CBD, yet the residential blocks immediately behind those main streets remain almost entirely single-dwellings or aging walk-up flats built before 1980.

With the NSW median house price sitting at roughly $1.4 million, Canterbury-Bankstown represents one of the few patches of inner-to-middle-ring Sydney where standalone houses still trade below $1.1 million, though that gap has narrowed sharply since 2022. A terrace on Unwins Bridge Road in St Peters sold for $1.78 million at auction in May 2026, illustrating how quickly investor money moves down the corridor when supply stays tight.

Councils, Residents and the Fight Over Character

Canterbury-Bankstown Council has historically pushed back against density mandates from Macquarie Street, and the current proposal is already generating organised opposition. Resident groups in Hurlstone Park, where Crinan Street retains a dense canopy of jacaranda and liquidambar, have raised concerns about heritage streetscapes and stormwater capacity in submissions lodged through the NSW Department of Planning's Have Your Say portal.

The exhibition period runs until August 29, 2026. If the rezoning is finalised without significant amendment, industry analysts expect developers to begin consolidating lots, acquiring two or three adjoining homes to assemble development-ready parcels, within months of gazettal. That process has already begun informally around Canterbury Station, where several terraces on Wonga Road have changed hands at prices that make sense only if buyers anticipate a higher and better use.

Dulwich Hill presents a particular flashpoint. The suburb borders the Inner West Council area, which operates under a separate planning instrument, and residents there have grown accustomed to design guidelines that prioritise low-scale streetscapes compatible with the heritage precinct around the Dulwich Hill tram stop, one of only two surviving sections of Sydney's old tram network. Any rezoning affecting lots straddling the LGA boundary will require close coordination between the two councils and the department.

For buyers, the practical calculus is uncomfortable but clear. Anyone purchasing a house within the 400-metre catchment of the seven named stations should seek specific advice on whether their block falls within the proposed rezoning boundary before exchanging contracts. The NSW Planning Portal's online mapping tool allows address-level checking, though the exhibited maps are still draft documents and boundary definitions can shift before gazettal. Buyers who secure properties in the affected zone before any rezoning is formalised carry both upside and risk, upside if the rezoning proceeds and land value lifts on development potential, risk if community opposition forces significant boundary pull-backs that leave their block outside the final controls.
