Diving in Townsville & Magnetic Island
Townsville is the gateway to the SS Yongala, the 1911 passenger steamer that is Australia's most celebrated wreck dive, and to the John Brewer and Lodestone reefs offshore. Magnetic Island, 20 minutes away by ferry, has shore dives on the SS Moltke wreck in Geoffrey Bay, the Museum of Underwater Art sculptures and fringing coral around the bays.

THE LOCAL PLANNING BRIEF
Understand the options around Townsville & Magnetic Island
Three different reasons to choose the Townsville region
Townsville is a mainland gateway for reef travel; Magnetic Island offers an island-based setting; the SS Yongala is a separate wreck objective. Tourism and Events Queensland describes these as distinct experiences, alongside the Museum of Underwater Art at John Brewer Reef. Start by choosing the kind of outing you want. Then check the operator’s actual departure point rather than treating every regional listing as an island day trip.
One useful question: Is our booking for local island diving, an offshore reef or the Yongala, and where does that exact product depart?
| Your interest | Research next | Keep in mind |
|---|---|---|
| Magnetic Island base | Compare island accommodation with the meeting point for the proposed activity. | Ask whether a mainland transfer is needed. |
| Reef or underwater art | Request the proposed reef and activity, including arrangements for non-divers. | A regional attraction does not guarantee that every boat visits it. |
| Yongala objective | Discuss the wreck itinerary and experience requirements directly with the provider. | Keep this booking separate from assumptions about an introductory reef experience. |

How do I choose a dive in Townsville & Magnetic Island?
Begin with the individual site and its source notes, then discuss the proposed trip with a local provider. The 42 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 Townsville & Magnetic Island 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.
