From the Release Notes (1.22.2.0) World Update VII: Australia:
Bush Trip
- Tasmania
- Southeastern Australia
- Sea to Desert
- Great Barrier Reef
- Northwestern Kimberly Coast
I think these map to:
Bush Trip
- Tasmania → TASMANIAN ODYSSEY(George Town to Launceston)
- Southeastern Australia → AUSTRALIA SOUTHEASTERN (Canberra to Melbourne)
- Sea to Desert → FROM THE SEA INTO THE DESERT (Whyalla to Coober Pedy)
- Great Barrier Reef → NORTH QUEENSLAND COAST (Cairns to Hamilton Island)
- Northwestern Kimberly Coast → NORTHWESTERN KIMBERLEY COAST (Derby to Kununurra)
I haven’t flown the Great Barrier Reef → NORTH QUEENSLAND COAST (Cairns to Hamilton Island) bush trip yet.
