Australia covers 7,688,287 km², sixth largest in the world, and close to 4,000 km separate its east coast from its west. Nearly 28 million people live here, about 80 per cent of them within 25 km of a mainland coastline 35,821 km long — which is the fact that governs any trip taken across it. The cities form a rim around an interior that stays largely empty; Sydney and Melbourne pass five million each, and Canberra, the capital, is neither of them. Six states and ten territories, and a sensible visit chooses two of them rather than the map.
