Google has brought its all-seeing eyes to Australia mounted on a backpack contraption called ''Trekker'', and plans to collect imagery of places only accessible by foot to incorporate into Street View on Google Maps.

On Tuesday, a Google employee captured scenes along the Bondi to Bronte walk in Sydney, using Trekker, which looks like something from outer space and captures images every 2.5 seconds with 15 cameras that are five megapixels each. Trekker weighs 18 kilograms and its cameras are situated about 60cms above the head of its collector.

The images it produces allows Google Maps users to virtually explore the locations it visits.

Google Australia spokesman Shane Treeves said the internet search giant had two trekker devices in Sydney and hoped to take them to some of the state's most famous locations, starting with Bondi Beach, Jervis Bay and Manly Beach.
