Google Australia announce the availability of following two features:
Road Traffic Information on Google Maps, available previously in Sydney, Melbourne, Brisbane and surrounding areas is now also available in Perth and Adelaide.
"To turn traffic information on, click the button labelled 'Traffic' next to the 'More' button at the top left of Google Maps. The colours you'll see overlaid on the roads correspond to the speed of traffic (relative to the speed limit of the road): green is free sailing, yellow is medium congestion, red is heavy congestion, and red/black is stop-and-go traffic. The information is updated every few minutes."
Google Maps for Mobile 5 is also available today, including some new exciting features: 3D maps, allowing you to zoom in and tilt maps, and 3D interaction, and offline access and rerouting for Google Maps Navigation. You can read more about this over here.
