About converting WGS 84 to GDA94 / Australian Albers
Converting from WGS 84 (EPSG:4326) to GDA94 / Australian Albers (EPSG:3577) is the standard projection for nationwide thematic mapping of Australia — Geoscience Australia, ABS, BoM, CSIRO. The Albers Equal Area Conic projection on GDA94 preserves area across the continent, making it suitable for landscape-scale ecology, fire, and statistical analysis.
The GDA2020 equivalent (EPSG:9473) is gradually replacing this in new datasets. For data already in EPSG:3577 the conversion is straightforward; the datum difference between GDA94 and WGS 84 is roughly 1.8 m due to Australian plate motion since 1994.
Why people convert EPSG:4326 to EPSG:3577
- Geoscience Australia continental thematic maps
- ABS Statistical Area boundaries
- Vegetation, fire, ecology raster analysis
- BoM climate raster products at continental scale

Frequently asked questions
- Should I use EPSG:3577 or EPSG:9473?
- EPSG:9473 is the GDA2020 equivalent of EPSG:3577, recommended for new work. The legacy EPSG:3577 dataset library is enormous and remains in active use; check the dataset's metadata.
- How accurate is converting WGS 84 to GDA94 / Australian Albers?
- Projection-only conversions are accurate to floating-point precision. If a datum shift is involved, browser-based tools use Helmert parameters which are accurate to roughly 1-5 m; for surveying-grade work apply the official grid-shift transformation in a desktop GIS.
- Does my data leave the browser when I use this converter?
- No. All coordinate transformations are computed locally in your browser using proj4js. The coordinates you enter are never transmitted to any server.
