Planning Reforms Target Data Centre Sites in Canberra Suburbs, Pressuring Local Property Values

The ACT government on 8 July 2026 released fresh planning directives that mandate 500-metre buffer zones around any new data centre developments in the Gungahlin district and parts of Belconnen.

These rules arrive as national data show buyers already knocking $35,000 off offers near similar facilities, and Canberra’s auction clearance rate sits at 65 percent with vacancy rates below 1 percent across the rental stock. Public servants who form the bulk of local purchasers now face extra checks on title documents before they bid.

Zones under review

The directives directly touch land near the Mitchell Industrial Estate and the planned extension of the Gungahlin Town Centre Master Plan. Properties along Aikman Drive in Belconnen and the northern edge of Evatt now sit inside the new buffer maps issued by the Environment Planning and Sustainable Development Directorate. Agents report that several listings in those streets have already moved from auction to private treaty after the maps appeared online last week.

Median house prices across the ACT stand at $835,000, yet local valuers note a 4 percent softening in the past quarter for homes within one kilometre of proposed data sites. The low vacancy figure and steady public service payrolls have kept overall demand firm, but the new buffers add a layer of uncertainty for buyers who previously ignored industrial zoning.

Next steps for purchasers

Anyone inspecting in Gungahlin or Belconnen should request the latest overlay maps from the Directorate before signing contracts. Settlement periods of 60 to 90 days still give time to confirm whether a site falls inside a buffer, and some lenders have begun asking for these checks as standard conditions. The next round of planning amendments is scheduled for September, when further adjustments to the Belconnen Town Centre precinct could shift additional streets into restricted zones.
