Another in our occasional series of history...

Travelling towards Murray Bridge we spotted this oldie across the highway from a highway rest stop.
Who lived here?
How long ago did they vacate the building?
Why did they leave?
Are the nearby ruins of a well or a water tank from times long gone?
So many questions so few answers, so if anyone can fill us in on some history it would be greatly appreciated.
