EOTopo is released as a new map edition each year to reflect how Australia continually changes. Roads, tracks, access conditions, land use and
infrastructure are never static, and relying on outdated maps can quickly lead to incorrect assumptions once you’re on the ground.
Each annual EOTopo edition includes improvements across the entire map — not just major highways or populated areas. Updates typically include:
- New and changed roads, tracks and access routes
- Updated sealed and unsealed road surfaces
- Walking tracks, hiking trails, cycling routes and MTB parks
- Urban growth, including new streets, bridges and developments
- National Parks, reserves and changes to land access
- Indigenous Protected Areas (IPA) and other land boundaries
- Water features, pipelines, powerlines, masts and towers
- Corrections and refinements based on field research and user feedback
A core part of this work is the ongoing maintenance of the ExplorOz Topo Roads dataset — a long-standing, Australia-wide database focused on minor roads and tracks. This dataset includes many remote, low-use and regional access tracks that are often missing, outdated or poorly represented in other map sources, yet are critical for touring, 4WD travel and outback navigation.
EOTopo is designed to work across multiple map scales, from broad regional planning down to detailed local navigation. Each annual update not only adds new data, but also refines how features appear, simplify or reveal additional detail as you zoom in and out — ensuring the map remains clear, readable and meaningful at every scale.
Each year’s EOTopo edition is produced by carefully comparing and merging multiple authoritative data sources, validating changes, and refining the map as a complete, unified product. This whole-of-map approach ensures consistency, accuracy and usability across the entire country.
All maps shown on the ExplorOz website — including
Places,
Routes,
Track Logs, Tracker and the EOTopo online map viewer — always display the latest EOTopo edition.
Purchasing updated EOTopo editions for offline use in the
ExplorOz Traveller app helps ensure you’re travelling with current, reliable map data — particularly important as access conditions, land boundaries and track availability continue to change across Australia.
