Rottnest Island Boat Dive Day Trip with Lunch

This full-day boat trip from Fremantle is aimed at certified divers who want to explore Rottnest Island’s marine life, caves and swim-throughs without organising the logistics themselves. The draw here is the underwater terrain: limestone formations shaped by ocean currents, with crevices, caverns, soft corals and varied fish life. Lunch is included, and snorkellers can join too, making it a workable option if not everyone in your group is diving.

You’ll head out by boat from Fremantle to dive sites around Rottnest Island. The trip includes two boat dives, with one air cylinder supplied, so you’ll need to bring or hire a second cylinder for the second dive. Conditions and site choice will depend on the day, but the focus is on exploring the island’s cave-like limestone features and marine life. If you’re snorkelling rather than diving, you won’t be dropped on the same deep site as divers; instead, crew use a tender to take snorkellers a short distance to nearby spots suitable for viewing from snorkel depth. This is an active day on the water and you’ll need at least moderate fitness.
