AUSTRALIAN DESTINATIONS
Diving in External Territories
Explore 169 listed dive sites and find the local knowledge to help plan your visit.
THE LOCAL PLANNING BRIEF
Research each territory as its own destination
The external-territory collection groups geographically separate destinations for directory browsing. Christmas Island, Cocos (Keeling) Islands, Norfolk Island and offshore reef records do not form one convenient travel region. Open the individual region page and build a separate transport, access and operator plan for that destination.
Choose the setting, then the trip Counts describe published records, not bookable trips or confirmed open sites.
There are 169 published site records across External Territories. The recorded categories include reef (51), wall (45), pinnacle/bommie (18), drift (13). These categories reflect the database; they are not a ranking, a conditions report or an assessment of your suitability.
Start with one of the regional pages below. State-wide totals are useful for browsing, but the actual choice should be made at the level of an operator, a site and a proposed itinerary.
Research operators in External Territories →Ask before booking
- Which territory and jurisdiction does this itinerary visit?
- What park or access permissions apply to the exact location?
- What is the contingency if transport changes?
Save the answers with the contact name and date. Separate confirmed arrangements from items still waiting for a reply.
Record your trip questions →Island stays
Confirm the route, accommodation, equipment availability and actual departure schedule with local providers. Do not assume a mainland travel pattern applies.
Offshore reefs
A mapped reef may have restricted access or no ordinary visitor departure. Check the responsible park manager and the operator’s permitted itinerary.
Contingency planning
Keep time and budget flexibility around transport. Identify which bookings depend on another service arriving as planned.
Questions, answered
How do I choose a dive in External Territories?
Begin with the individual site and its source notes, then discuss the proposed trip with a local provider. The 169 published records are research options, not a list of trips available today. Match the plan to your training, recent experience and the operator’s current requirements.
When should I visit External Territories for diving?
Choose dates with a provider who runs the activity you want, then discuss seasonal patterns, recent conditions and alternative itineraries. A generic best-month claim cannot establish the conditions at your exact site or guarantee a wildlife encounter.
Can I use these maps to enter or navigate a dive site?
No. Recorded and approximate map positions support orientation only. Confirm the exact access, permissions, meeting point and route with the responsible local provider or manager.
