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.
