In short
Short answer: the Buffer Area Overlay (BAO) is a Victorian planning overlay set out in clause 44.08 of the Victoria Planning Provisions and applied to land through each council's planning scheme. In the clause's own words, its first purpose is: “To identify buffer areas where there is potential for off-site impacts on human health or safety, or significant off-site impacts on amenity, from industry, warehouse, infrastructure or other uses”. (Department of Transport and Planning (Victoria), verified 27 Sep 2026)
An overlay sits on top of the land's zone and adds controls for one issue, whatever the zone is; a lot can carry several.
What it typically means for a buyer (Delora editorial, not legal advice): A buffer around a use with potential off-site impacts, such as industry or a treatment plant.
Check whether the Buffer Area Overlay applies to an address with Address Check. For a decision on a specific property, the official record is a Planning Property Report from VicPlan, and the council's schedule sets the local detail.
