Optus prepares coverage maps using the latest available data, tools and techniques to map Optus mobile coverage as accurately as possible. However as with any network based on radio technology, handset quality or local conditions may prevent or interfere with mobile reception within coverage areas, for example, inside concrete buildings, lift wells, basements, tunnels and road cuttings. High rise buildings may also suffer degradation of service. These maps are not an indication of in-building coverage.
Optus’ coverage maps may show planned rollout, which is indicated on the map. These predictions are based on rollout schedules available at the time of publication and may be subject to change without notice as circumstances require.
