Find your property boundary online, free (SA, VIC, QLD and TAS)

Every title in Australia has a surveyed boundary, and most states publish a digital version of those boundaries (the cadastre) that anyone can look at for free. It is the quickest way to see roughly where your block starts and stops on a map.

Where to look

South Australia: the SA Property and Planning Atlas (SAPPA) shows parcels with their plan and allotment numbers.
Victoria: VicPlan, built on Vicmap Property.
Queensland: Queensland Globe, with lot on plan numbers.
Tasmania: theLIST.
New South Wales: the NSW Spatial Viewer (formerly SIX Maps).

In Plotlay, Map → Suggest site boundary fetches the parcel from the SA, Victorian, Queensland and Tasmanian services and draws it on your project, with the lot and title details in its notes. (In SA, for example: "Allotment 20, D677, CT 5756/911".)

How accurate is it

Good enough to plan with, not good enough to argue a fence line. Digital cadastre is compiled from survey plans of many ages; in established suburbs it is usually within a metre or so of the true boundary, sometimes more in older or rural areas. Fences themselves are often not on the boundary at all.

When you need a surveyor

Building close to a boundary, a dispute with a neighbour, a new fence on the line, or a subdivision: get a licensed surveyor to peg it. The online boundary is the starting point for that conversation, not the answer.

Line your photo up with it

The boundary is also the best thing to line an aerial photo up against, because photos are often a few metres out. See why satellite images don't line up.
