This footage is a highlight reel from the 2015 Steadfast Outback Air Race. The race is held every three years to raise funds for the Royal Flying Doctor Service. You wouldn't know from this video: it seems to be all about logging time over some of Australia's best geography whilst finding the most idyllic places to chill out and have a good laugh. I thought fund raising was all lamingtons and chook raffles; this lot seem to have redefined it.
