Hi mate
I salute you!
When I lived in WA, light aircraft were everywhere. We used a C172 for mustering as did many of the stations in the Upper Gascoyne and Pilbara. Now, I'm wondering where they have all gone or, more pertinently, how they got there? It is bloody hard to find airports with avgas over there now; many only have avtur or nothing.
I'm planning a trip over there for late July/early August. Have a conference to go to in Fremantle but also want to see the old place in the north-west. I'd really like to go the long way around the top, but it is a long way and I'm older than you :-) So I might just take a more direct route and go across to the Alice, then Meeka to Mt Augustus and Carnarvon before turning south down the coast.
Anyway, good to talk. Hope someone sees Robbo's post and contacts you.
