Diving in Tiwi Islands
The Tiwi Islands north of Darwin have a handful of wrecks and reefs, dived occasionally by Darwin charters in the dry season. Permits are required and crocodiles are present.
THE LOCAL PLANNING BRIEF
Understand the options around Tiwi Islands
Northern Territory records require particular care in how they are used. The NT Government warns that crocodiles occur in coastal, harbour and river environments. A site appearing in this directory is not a recommendation to enter the water. Research the exact activity with a qualified local provider and follow current official access and crocodile-safety guidance.
What this regional directory records Counts describe published records, not bookable trips or confirmed open sites.
There are 2 published site records in Tiwi Islands. The recorded categories include wreck (2). These categories reflect the database; they are not a ranking, a conditions report or an assessment of your suitability.
Use the Tiwi Islands site cards to compare recorded access and depth, then open the individual pages for the map accuracy and source notes. Sites grouped in a region are not necessarily close enough to combine in one day.

Record your trip questions →Questions, answered
How do I choose a dive in Tiwi Islands?
Begin with the individual site and its source notes, then discuss the proposed trip with a local provider. The 2 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 Tiwi Islands 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.
