Many people I meet do not understand that the Australian continent is roughly the same physical size as a mainland USA.
The Mapfrappe website uses Google Maps to show exactly this:
FWIW, my home town (Brisbane, Queensland) is roughly the size of South Carolina and I've been on properties (what some people call 'farms' or 'ranches') that are larger than entire US states.A typical jet flight takes 6.5 hours to fly from Brisbane to Perth, the two state capital on west and east coasts.
