Really good read from a guy who recently flew a single lancair US-Aus here:

All I can say is your two favourite colours must be blue (sea) and gold (sand)
Nearly the same size as the continental USA, just we have a lot of sand in the middle.
Oh, and a big rock.
Population about 25 million people , Tee up your airport connections - it ain't like the USA where every aerodrome has a rental car and attended fuel.
South east coast has best flying conditions around Easter. Qld gets a bit tropical during the build up (Nov+)
Plenty of good places to visit , plenty of remote places to visit - million acre stations (farms)
I reckon the container is a great idea - It'd reduce the personal risk, and keep one fresh (er) for the circumnavigation
In no particular order
Tasmania (cradle mountain worth a peek) or simple, King island
Apollo Bay
Merimbula has great facilities and close to the beach
City of melbourne will have people - (Moorabin or Essendon?)
Anywhere along the great barrier reef (Hamilton island?)
Kakadu
Ningaloo reef
Wirrealpa station
Birdsville hotel (for the horse race?)
Broken Hill ( good source to keep the noise going) for a couple of outback stations ie Trilby station (Darling river),
Noccundra Hotel, Kallara station
I've left some big gaps in that lot - maybe someone else will fill them in !
