About this tour
An 8-hour boat dive day trip from Fremantle to Rottnest Island, combining two scuba dives with snorkelling options and lunch. The limestone island's soft rock has carved dramatic caverns, swim-throughs and crevices you won't find on typical reef dives. Divers get one air cylinder supplied; snorkellers are ferried to adjacent shallower sites. Best suited to certified divers comfortable with exploratory cave features and moderate physical exertion.
Highlights
- Two boat dives with one air cylinder supplied per diver
- Dramatic limestone caverns and swim-throughs, not standard coral reef
- Snorkellers welcome — tender takes you to shallower adjacent sites
- Buffet lunch and morning/afternoon tea included
- Soft coral and diverse fish life throughout Rottnest waters
- Departs from Fremantle, close to Perth city
- All scuba and snorkelling equipment provided or hire available
What to expect
You'll meet at Fremantle port and board a dive boat heading to Rottnest Island. Morning tea is served en route. The day includes two separate dives; you'll use one supplied air cylinder and can hire or bring a second. Between dives, you'll have lunch and break time on the boat. Snorkellers board a tender to shallower sites near the main dive locations and can explore at their own pace. Afternoon tea rounds out the day before the return to Fremantle. Total time on water is roughly 8 hours; actual bottom time varies by site and group pace.

Good to know
This suits certified scuba divers who want to explore beyond shallow reefs, and snorkellers content to view from 5–8 metres depth. You'll need moderate fitness — descending, swimming through caverns and navigating currents demand endurance. Not suitable if you have spinal injuries, are pregnant, or have cardiovascular concerns. The boat can be choppy; sensitive swimmers should factor in seasickness risk. One air cylinder is included; a second costs extra (hire or bring your own). Rottnest Island landing fee applies only if dropped ashore after the dive. Dietary requirements need 24 hours' notice. Group size varies; expect 8–20 divers typical for dive boats of this type.
