The Volga was an iron ship wrecked on the reef between Double Island and Mac Point in Torres Strait. Marine Life Network's Torres Strait page describes it as a rarely visited wreck lying in 5–10 m, consisting of a jumble of debris patrolled by lots of schooling fish. The date of the wreck and the vessel's history are not given in the sources read.

Torres Strait has claimed many ships over the centuries – its maze of reefs, shoals and fast tidal streams made it one of the most dangerous passages in the world for sailing ships and early steamers. The Volga is one of numerous iron-hulled vessels whose remains now lie scattered on its reefs. The wreck is broken up rather than intact, so the dive is about poking through plates, frames and fittings on the reef rather than exploring a hull.

The debris provides structure that attracts fish, and schooling fish are the main living attraction. The shallow depth allows a long dive, but the strong tidal currents mean it must be timed for slack water. Local knowledge is essential both to find the site and to manage the tides, and Torres Strait's crocodiles are a real hazard.

Access to reefs and islands should be arranged with the respect of traditional owners. The Volga suits wreck enthusiasts visiting Thursday Island who can arrange a local boat. It is not a scenic reef dive; its value is historical and as an example of the region's many rarely seen wrecks.

As a wreck likely more than 75 years old, it is protected under the Underwater Cultural Heritage Act 2018.

Fly Cairns–Horn Island (daily Qantaslink/Regional Express services, about 1 hr 45 min); Horn Island airport links to Thursday Island by a 15–20 minute passenger ferry. There is no full-service dive shop in Torres Strait, so diving is arranged either on an expedition liveaboard (Mike Ball's Spoilsport ends or starts its November Northern Exposure trips at Horn Island Pier and has dived the Quetta; PDS's MV Kalinda has also finished trips there) or through local contacts and club divers on Thursday Island with a local boat. Bring all equipment; fills are limited and must be arranged in advance.

Torres Strait is a shallow, tide-dominated passage between the Coral Sea and the Arafura Sea, and the tides drive everything. Currents in channels such as the Adolphus, Prince of Wales and Endeavour channels regularly exceed 4 knots, and sites are only diveable for a short slack-water window – often once a day, and sometimes not at all on big spring tides. Plan around neap tides and consult local tide tables for the exact slack.

The south-east trades blow strongly from about April to November, raising steep wind-against-tide seas; the calmest period is the transition around November–December (when liveaboards visit), and the north-west monsoon season (December–April) brings storms, cyclone risk, stingers and reduced visibility from run-off. Visibility is variable, typically 5–15 m, and is best on the flood tide during neaps.

At slack water, descend onto the reef and wreckage in 5–10 m and swim slowly through the debris field, watching for schooling fish; return to the boat before the tide turns.

No regular operator – a rarely visited wreck reached with local boats and knowledge from Thursday Island.
