Wyalkatchem Airport, Wyalkatchem, Western Australia 6485
Yeah it is a bit of a trek, but the tickets ain't expensive and I am sure you can take your own drinks and food? I haven't checked that but its only 2.5 - 3 hrs on a good run probably with a little pit stop half way.
Now I never been anywhere near that part of Australia before... so I am the wrong person to judge but I just go by what Google tells me.

So... anyone interested?
