Hmmm... Not sure I'd agree with this. A strip is only useful to you if you can glide to it (or a road or a flat open paddock) in event of engine failure. Assuming the glide ratio of something like a C 172 ( and windless conditions and great flying) you'd probably get about 8-10km from 3500ft.
In 'station country' land is often cleared, but there's an still awful lot of wilderness around parts of Australia, and going into the trees is not a desirable outcome by anybody's standards.
My place isn't particularly remote, but its 30 km to the nearest station strip and 10 km from the closest scrubby paddock or station track where you might attempt an out landing. But heading the other direction, no strip for 35km across thickly timbered and rocky escarpment country dissected by ravines and gorges. Tiger Country.
Several recreational and GA aircraft pass over my house each day, including station aircraft, trainee aviators doing navs, and charters out to indigenous communities. They mainly fly at between 3000-5000ft. I have often wondered what they would do in event of an engine failure over our country. My strip is primarily for my own use and approved visitors, but in event of an emergency overhead, it might just save a life.
