The Neptune Islands Marine Park is one of the world’s best and most accessible great white hotspots. Full-day cage diving tours depart year-round from Port Lincoln (and some include swims with sealions). In winter months, opt for 2-5 night liveaboards to allow for unpredictable weather and reduced daylight hours.
Best for ages: 18+ | £300 | 1-5 days
