Somebody was relating a story to me recently about getting latitude and longitude muddled up. It made me remember times when I've easily swapped the two over as they were so similar - think of working in Egypt (30 deg north, 30 east), Russia (50/60/70 deg north/east), Senegal (15 deg south, 15 west)... I could go on but get the point?
I doubt if anyone working in Oceania has these issues. Think about it.
