Board a three-deck catamaran from Cairns for a two-day, one-night liveaboard that visits outer-reef moorings like Saxon and Norman. This trip pairs guided snorkels and night experiences with onboard meals and air-conditioned cabins.
More ways to explore the area's outdoor wonders
You step off the marina jetty and the catamaran hums to life — three decks of open sun, a dive platform that dangles over water the color of crushed aquamarine. OceanQuest slips past the coastal fringe, and by evening the reef lights come alive beneath a star-strewn sky: plankton shimmer, fish scatter, and the hull becomes a slow-moving window into another world.

Conservation
The Great Barrier Reef faces warming and bleaching events; operators follow mooring, waste and sunscreen guidelines to reduce visitor impact.

Bring a fitted mask
A well-fitting personal mask reduces fogging and jaw fatigue; loaner gear is available but fit varies.
Use reef-safe sunscreen
Apply mineral-based sunscreen before boarding and reapply after swimming to protect coral and reduce harm to marine life.
Hydrate and pace alcohol
Drink water between activities — ocean days and salty air increase dehydration — and limit alcohol the night before snorkeling.
Prep for seasickness
If you’re prone to motion sickness, take preventative medication before boarding and choose a mid-ship cabin for the smoothest ride.
Personal snorkel mask
Better fit and seal than shared rentals, reducing fog and leaks.
Reef‑safe sunscreen (SPF 30+)
Protects your skin and the coral ecosystem from chemical runoff.
summer
Rash guard or thin wetsuit top
Provides sun protection and warmth during early-morning or cooler-season swims.
winter
Reusable water bottle with carabiner
Keeps you hydrated on deck and reduces single-use plastic waste.
