The Royal Flying Doctor Service is giving donors a chance to claim a patch of the Australian sky.
Demand for the flying doctor service has grown by more than a quarter in the past seven years as the mining boom sent more people into remote areas.
The famous flying doctors are now launching their biggest ever fundraiser on Monday in a bid to secure their long-term future.
A $50 donation gives people a chance to put their name on a piece of sky on the Royal Flying Doctor Service flight paths.
They can then choose to get weekly updates of the lifesaving doctors' activity in their patch.
While supported by the commonwealth and state governments, the service - which ensures no patient is more than two hours from medical help - relies heavily on the community."Buy the Sky" donations will be used to purchase and equip aircraft, and to finance major capital initiatives.
