I always feel that I am right out of Melbourne by the time I get to Wallan Northbound, although the suburbs are doing their best to try and reach here.
There are a lot of security cameras around, so the best thing is to drive to the northern end of the car park and start from there.
This is a replacement cache as the last position was starting to ge a bit overun with more blackberries (again). Hopefully this spot will last a bit better.
