I'd say they are pretty similar in most respects. But geography is a big difference that is relevant to Covid-19. Autrstial probably didn't have community spread of covid until Late Feb. But America had community spread in at least mid Jan--and probably earlier. But Australia locked down essentially when America did. If they can eradicate the disease, that's a huge win, but if they can't they are just delaying what happened in America.
