Seabirds, whales, sea lions and other marine wildlife inhabit the lagoons, reefs and small islands of Marmion Marine Park.
There is good diving throughout the year, depending on daily weather. Boyinaboat Reef, just 75 metres from Hillarys Boat Harbour sea wall, is a popular dive site, while Mettams Pool offers safe snorkelling close to shore.
You need a boat and scuba gear to explore North Lump, Wreck Rock, Cow Rocks, Wanneroo Reef and many other submerged reefs within the marine park. The wreck of the Centaur also makes an interesting dive.
Boating, swimming, whale watching kite and windsurfing are all popular. You are welcome to fish in most areas within the marine park (those outside sanctuary zones – see map) but first check the latest size, season and bag limits (www.fish.wa.gov.au). Breathhold spearfishing can be undertaken outside sanctuary zones in areas at least 1800 metres off the shore. Spearfishing using compressed air is not permitted.
Private dive charters operate for most of the year and diving instruction is available. Whale watching charters leave from Hillarys at the peak of the humpback migration, from September through to November. Fishing charters are also available from Hillarys Boat Harbour.
- Scuba diving and snorkelling have claimed lives and divers should never become complacent about safe diving practices.
- Swimming into caverns and under ledges can be hazardous.
Take care to avoid boat traffic and be sure to tow a dive flag.
