Just a few in no special order that spring to mind
Catch a 1mt + barra
Do the Simpson, Cape, Kimberley's, CSR at least once each
Climb the "Rock"
Swim with a Whale Shark
Live on the road for an undetermined time
Watch my kids grow up healthy and happy and outlive me
Live on an outback station for at least 12 months
there's probably a thousand more if I sit here long enough
