How to dfind Land Value in Victoria for a property

Hi Fellow members
I have heard one of the important factors when buying an IP is to look at the site value/purchase price ratio. Higher the better i.e. more money going towards the land component and less for the house component. Qld government provided their QLd globe, NSW govt provides NSW globe which you can then layer over google earth and you can find out the land value of the property you are looking at. Can anyone tell me how to find similar info for properties in Victoria(Melbourne).

many thanks in anticipation.
