On the Brink: Harkness Avenue’s Rezoning Could Transform Deer Park’s Overlooked Gem

Deer Park’s Harkness Avenue corridor is poised for a dramatic change as City Council prepares to vote on a long-awaited rezoning proposal later this month. If approved, the plan could unlock medium-density development along a two-kilometre stretch abutting Harkness Reserve, shifting the suburb’s status from overlooked to investment hotspot almost overnight.

This push for rezoning comes amid heightened demand for new homes and renewed council efforts to revitalise underutilised sections of Deer Park’s western fringe. With buyers struggling to secure affordable options in nearby Parkview and Florin, attention is turning to Harkness Avenue-home to modest post-war weatherboards, derelict corner sites, and a handful of industrial warehouses that have sat largely unchanged for decades. Recent speculation has seen local property forums buzzing about the potential windfall for current owners and a rush of off-market offers from developers.

Local Identity, Anchored by Community Landmarks

Anchored by the leafy expanse of Harkness Reserve and its popular weekend markets, the precinct has retained a distinctly local character despite its proximity to the Deer Park railway station. For years, little changed at the corner of Harkness Avenue and Vine Street, where the Deer Park Bowls Club and the much-loved Little Olive café draw crowds every Saturday morning. The prospect of rezoning is fuelling debate among residents who recall earlier failed renewal plans, particularly after the former tyre yard at 47-53 Harkness Avenue languished for years following its closure in 2018.

Local developer interest is being closely watched. City Planning’s June proposal would allow for townhouse and low-rise apartment developments up to four storeys on earmarked sites, replacing older homes and disused light industrial blocks. The plan cites transport links-most notably the extension of Bus Route 418 to Harkness Reserve in early 2025-as a key driver for future growth. According to data from Deer Park Council’s 2025 Urban Assessment Report, the average sale price for a three-bedroom home along Harkness Avenue climbed from $612,000 in 2022 to $701,000 in the first quarter of 2026, reflecting increased activity well ahead of the zoning decision.

What Next for Homeowners and Investors?

The upcoming council vote is scheduled for July 22 at the Deer Park Civic Hall. If successful, landowners can expect a formal planning amendment process to commence within weeks. For those considering buying in the precinct, local buyer’s agents say action remains brisk but measured, with potential for price growth especially on sites within 400 metres of the reserve and primary transport nodes. Council’s online planning portal is set for an upgrade in August, promising clearer guidance on permitted densities and required open space allocations.

With open houses in the coming fortnight already booked solid, and speculative letters landing in mailboxes along Harkness Avenue and Knox Street, momentum is building. Whether this pocket of Deer Park remains a quiet local enclave or emerges as a model of gentle density could hinge on council’s July decision-and the speed with which investors act in the weeks ahead.
