Tracing a life in the bush

Couple of years ago I asked a similar question to that detailed below. Unfortunately no body could help at the time.

I'm looking for a town or property called Sandilands (Sandylands?) in SA. We worked there back in the late 50's and early 60's. My memory is not particularly good, so bear with me.

It was in the wheat belt (with some cattle) country. We were "rock picking" at the time. I remember the old man making reference to work on Kangaroo Island, so I'm assuming it could be some where at the Southern end of SA.

The owner of the property was a fella called Gerzts (or similar German name).

The reason I'm asking this is because I wouldn't be here now if it wasn't for his quick thinking. I'd like to track the family down to say thanks.

We also lost a good mate who was crushed by a Bull in the stock yard and I'd like to visit his grave.

Any help you can provide would be much appreciated

Regards

Kim
