For people living in Australia's harsh and remote outback, aeroplane services are a vital link to the outside world. Matthew Brace goes along for the ride. From her front porch Dorothy Wilhelm looks out over big fields.
Dust devils leave balls of windmill grass gambolling in their wake.
On windy days so many balls of it get snagged on the wire fences that they look more like bushy hedgerows. In winter the sun does little to ease the ice-cold wind whipping out of the desert. Just out of view, over a ridge by a lone eucalyptus tree, a herd of 60 or so sheep brave the dust. Even the tireless sheepdog Pearl is weary of the gale as she hitches a ride on the motorbike back to the farmstead with Dorothy's son Chris after mustering the flock. The 21,600-hectare farm has 4,500 merino sheep and 180 cattle.
