We chose Western Australia from these criteria: Good snorkeling, possible to do in ~14 days time, beautiful scenery, unique nature (like the Kalbarri and Ningaloo Reef), lots of wildlife (kangaroos) and nice beaches.

Exploring Kalbarri Wildlife with an Autocamper
Kalbarri National Park is a grand place that took my breath away - it felt surreal standing in the middle of this huge canyon. It was my second favorite place along the West coast of Australia, only beaten by the Ningaloo Reef in Cape Range National Park in the very north-western corner of WA.
