Ex-HMAS Tobruk

High risk: Depth hazard

Wreck sits at up to 28.5 m depth on starboard side — requires advanced scuba certification; snorkellers limited to surface viewing.

High risk: Pentrating wreck hazards

Wreck interior has entanglement risks, silt, and limited exits; penetration requires advanced wreck diving certification.

High risk: Wreck Penetration Hazards

Enclosed spaces, sharp metal edges, overhead environments, silt-out risk, and entanglement hazards inside the wreck compartments.

High risk: Restricted Access Area

Entry to the Ex-HMAS Tobruk designated area is prohibited without a permit or written approval — applies to all vessels, divers and snorkellers.

High risk: Depth and pressure

The wreck sits approximately 30 m below surface, posing decompression and gas narcosis risks for inexperienced divers.

High risk: Restricted access zone

Entry to the designated Ex-HMAS Tobruk area is prohibited without a permit or written approval — applies to all vessels, divers and snorkellers.

High risk: Depth — 27 metres

The wreck rests at 27m depth; requires recognised scuba diving qualification and strict dive planning. Snorkelling is not feasible at this depth.

High risk: Enclosed spaces / overhead environment

Penetration into the wreck's interior carries entanglement and entrapment risks. Only certain areas are open; advanced wreck training recommended.

High risk: Restricted Entry Zone

The entire ex-HMAS Tobruk area is a designated zone; entry requires a permit or written approval — recreational access is strictly controlled.

High risk: Restricted access without permit

The site is a designated area in the Great Sandy Marine Park; entry is prohibited without a permit or written approval from the managing authority.

Moderate risk: Strong currents & weather

Offshore wreck exposed to open ocean conditions; unpredictable currents and wind can develop quickly.

Moderate risk: Permit-only access zone

Entry to the designated Ex-HMAS Tobruk area is prohibited without a permit or written approval; applies to all vessels and divers.

Moderate risk: Strong tidal currents

Offshore wreck sites in the Bundaberg region can experience strong tidal flows that increase difficulty and reduce bottom time.

Moderate risk: Strong Ocean Currents

Open ocean site 40 km offshore subject to strong tidal and wind-driven currents that can quickly sweep divers away from the wreck.

Moderate risk: Weather-dependent conditions

Exposed offshore location subject to sudden squalls and wind shifts. Check BOM forecasts before departure.

Moderate risk: Depth hazard (30m max)

The wreck descends to 30 metres, requiring proper dive certification, decompression planning, and gas management for advanced divers.

Moderate risk: Weather dependency

Open ocean site exposed to squalls and wind shifts. Check Bureau of Meteorology forecasts before departure.

Moderate risk: Wreck Penetration Hazard

Internal spaces (tank deck at ~25 m) require advanced wreck-diving training; silting and entanglement risks inside the hull.

Moderate risk: Depth (30 m max)

Maximum depth of 30 m at the seabed requires dive qualification and careful gas management; decompression obligation risk.

Moderate risk: Wreck depth and decompression risk

The wreck rests at 12–30m, with sections reaching 37-47m for advanced divers, requiring strict dive planning to avoid decompression sickness.

Moderate risk: Depth & decompression limits

Wreck sits at 28.5m depth; requires proper dive planning, air management, and decompression stops.

Moderate risk: Strong currents

Ocean currents in the Wide Bay region can be strong, especially around submerged structures.

Low risk: Entanglement risk

The wreck has enclosed spaces including the hold, cabins, engine room and crane structure where entanglement is possible.

Low risk: Marine traffic

Located offshore in shipping lanes near Bundaberg; boat traffic and fishing lines pose a hazard.

Low risk: Offshore weather exposure

Located 31 km offshore; exposed to winds, swell, and changing sea conditions typical of the Wide Bay marine environment.

Low risk: Enclosed spaces and entanglement

The wreck's open tank deck and internal compartments present entanglement and entrapment hazards for divers who venture inside without training.

Low risk: Limited visibility

Visibility can vary significantly depending on swell and tidal conditions.

Low risk: Penetration hazards

Inside the wreck there are entanglement risks, sharp metal edges, and silt hazards for untrained divers.
