While we were on holidays we spent 4 nights on a working sheep station. They had 165,000 hectares and allowed us to wander around at our will.
We were invited to watch them work with some sheep in the yards and take some photos.

The station has easy access to Mungo National Park and the air-conditioned cabins were great.
