These shots were taken during a trip to the Abroholos Island which are 60 Km off the coast at Geraldton, about 400 km north of Perth. The islands are famous for the wreck of the Batavia which foundered on the reefs surrounding the islands in 1629. The wreck lies at 6 metres and is a good snorkel with anchors and canon clearly visible. The remains of the hull were recovered and are in Fremantle Maritime Museum.
The Lionfish is highly poisonous but is very solitary and slow moving so does not pose a threat to divers. Quite spectacular when you come across them.
