In short
Short answer: the Significant Landscape Overlay (SLO) is a Victorian planning overlay set out in clause 42.03 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 significant landscapes”. (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): Protects a significant landscape; the siting and look of new buildings may be controlled.
Check whether the Significant Landscape 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.
