One of my favourite places in Victoria is the Kara Kara, some beautiful pristine bush land and wild life in there with lots of hidden old boys diggings for the adventurous who are willing to put the time in looking for patches. A lot of the gold is associated with extremely weathered-down quartz reefs high on the hills, look for the deeper gravels on the ridge tops then detect the slopes where the wash has bled out over the sides into the deeper ground.
Don't let the water worn quartzes put you off, a lot of them have weathered in situ or very close to source. The ridges are there because they represent harder ground compared to the valleys, harder ground usually suggests quartz reefs or contacts. The key is to look for the junctions between heavily mineralised basalts (Blood red ground) and the paler heavily weathered granitic/sandstone areas which is the dominant soil type in the area, those contacts are the gold-ovens for nuggets being cooked up.

PS Not sure of the status of the allowable detecting areas around there these days.
