Before You Book

Difficulty: Moderate to High

This is a real expedition, not a beach holiday. Here is exactly what it asks of you.

  • Multiple domestic flights and ferry / island transfers
  • Long travel days across several states and island groups
  • Water-based activities on most days
  • Remote-island logistics with limited facilities
  • Weather-dependent marine activities
  • Multiple ecosystems and climates across one month

Diving Requirements

Scuba diving requires appropriate certification and medical suitability. Guests without certification can still join every snorkelling, lagoon, kayaking and reef-interpretation session, and introductory dives can be arranged with certified instructors where conditions allow.

The advanced and repeat dives on Day 28 are open to qualified divers. Tell us your certification level when you enquire and we will map the dive days to your group.
