Ok, yeah no. One wouldn’t use the private road between Bullyaninnie station and Oak Park station to head into town from Oak Park afaik.
I think it’s unsealed and would be strictly off limits to civilians or non family. Imo.
You’d take the Barrier Highway and go South West from Yunta town, then turn left onto Rucioch Rd just after Nackara, then keep going through to Bullyaninnie Road to arrive at the Bullyaninnie homestead if you wanted to travel from Yunta to Bullyaninnie. Then if you were driving to Oak Park station from Yunta you would probably take Netley Gap Sturt Vale Road and then veer right onto Oak Park Road to then arrive at the Oak Park homestead from there.
However if one was driving from Oak Park to Adelaide one may want to cut through the Bullyaninnie station, but I am honestly not sure how drivable that road between the two homesteads is. It might be more of a pathway you would use for an ATV, a motorbike or a horse, and not a car or ute as such. Of course, you couldn’t cut through the stations if you weren’t family or an invited guest as it’s all private property there and we know what happens when one steps foot into Oak Park property uninvited.

Of course, if someone who lives at Oak Park and is a suspect, for example, in a major crime, and was wanting to hide the body of a child - they might use a motorbike and not a car, so really they could have gone anywhere they liked…. In theory. They could have gone to Bullyaninnie.
