WA is so big you can do almost anything here except snow ski!
With a mamoth coastline and a reef second only to the Great Barrier reef, the state of Western Australia offers endless opportunity for a holiday like no other.
The Ningaloo reef can be accessed right from the coast so those long boat trips out to the reef aren't a necessary part of the deal.
The wine regions of Margaret River to the south are a foodies paradise and if jewellery is your thing well WA produces the best of the worlds gold, diamonds and Pearls.
However long you have allowed for your WA trip it won't be long enough.
