How to find your lot size in Australia

Search a covered Australian street address on MapMyLot to see the parcel area in square metres and hectares. The figure is calculated from mapped cadastral geometry and may differ from a title or listing. Five daily lookups are free with no account needed. Australian coverage includes:

• Queensland
• New South Wales
• Victoria
• Tasmania
• The ACT

Where the number comes from

Each state maintains its own cadastral dataset. MapMyLot calculates area from the parcel geometry in the loaded dataset. The result is useful for comparing land sizes, but it can differ from a surveyed or registered area because the geometry, parcel definition and source version may differ. Check the title or survey records when the legal area matters.

Perimeter and other measurements

Alongside area, the readout shows the perimeter in metres, and - where the address falls inside covered proximity data - straight-line distance to the nearest high-voltage power line, mapped flood zone, the coast, and the nearest park. These come from the same single address search, without a separate lookup per topic.

Why lot size matters before you buy or build

Lot size drives what is realistically buildable on a block, whether a subdivision is worth investigating, and how a listed area compares to what is actually on the title. Checking it directly from cadastral data, rather than trusting a listing's stated figure, avoids relying on a number nobody has verified.

Note: cadastral data is subject to positional variation by location and source dataset. For a figure that carries legal weight, confirm against the title document or a registered surveyor.

Free to check, Pro for unlimited

Five address lookups a day are free, with no account required - enough to check a handful of lot sizes. MapMyLot Pro, at A$19.99 a month, removes the daily limit and adds unlimited PDF boundary reports, useful for agents or buyers comparing lot sizes across several properties in one session. A single PDF report is also available for A$4.99 without a subscription.

Square metres, hectares and acres

One hectare is 10,000 square metres. One acre is approximately 4,046.86 square metres. For example, 2,000 square metres is 0.2 hectares, or about 0.494 acres. Convert both figures to the same unit before comparing a listing with the map.

For a listing that appears to show a different area, follow the block-size comparison checklist.

Check an address in three steps

1. Open the map, enter the street address and select the matching result.
2. Confirm the highlighted parcel is the one you meant to check, then read its area and perimeter.
3. Use satellite view for visual context and review the available readouts. If the parcel or figures do not match your documents, investigate the difference before relying on them.

What to do after your first check

Confirm you have the right parcel, then compare its mapped size and shape with the listing or your documents. If you need a copy for your own research, a one-off PDF property report costs A$4.99. For repeated checks, Pro costs A$19.99/month and includes unlimited lookups and PDF reports. Compare the options after checking the address. Reports are informational and do not replace a survey or title search.
