Simplified Cadastral Boundaries for Western Australia and Territories

Landgate provides a simplified digital representation of all land parcel boundaries for the State of Western Australia, including Cocos Keeling Island and Christmas Island. The dataset is intended for informational use and excludes attributes found in the full cadastral version.

Use Cases

• Analyze land parcel boundary shapes for spatial planning and administrative region mapping.
• Integrate simplified boundary polygons with other geographic datasets for base mapping.
• Use the boundary geometry to visualize the extent of Crown, Freehold, or other land tenure types.

Strengths

• Covers the entire State of Western Australia and two Commonwealth jurisdictions.
• Maintained by the authoritative Western Australian Land Information Authority (Landgate).
• Available in multiple geospatial formats including GeoJSON, SHP, and Geopackage.

Limitations

• Contains no attribute data, limiting analysis to geometry alone.
• Explicitly not for legal purposes, requiring original survey documentation for authoritative use.
• Simplified representation may not reflect the highest precision of original surveys.
