Australia is the sixth largest country in the world. It's about the same size as the 48 mainland states of the USA and 50 per cent larger than Europe, but has the lowest population density in the world - only two people per square kilometre.
Here is a more common picture of a Christmas Tree Worm; still fine looking! Taken on a nice dive trip out of Cairns, Australia.
