The mapping in parts of Victoria seems to be about 3 years old. There is a Van parked in our car park at work that we traded in in June 1996, and a sign at Sausage Gully on the Great Ocean Road that someone nicked about 18 months ago. Also, the house next door, that people moved into in January, is a vacant block.
Having said that, we drove behind a Mini Bus type vehicle, on the Great Ocean Road, 18 months ago, near Lavers Hill, that I am guessing was taking pictures for Google Earth and Mapping.
It had booms like extended side mirror sticking out sideways and some sort of scaffolding arrangement sticking out the front, which had a black box arrangement attached.
Unfortunately, I have no reference point in time, to look at images on this part of the road, and know if they were taken then.
