Wigram Island is one of the English Company's Islands, a chain of islands stretching north-west from the Gove Peninsula toward the Wessel Islands. It is mentioned by the Marine Life Network as a camping base used by Gove dive and fishing operators for trips to the offshore islands and reefs.

No dive-site-level description of Wigram Island itself has been published. Regionally, the English Company's Islands are surrounded by fringing coral reefs and channels where tidal streams concentrate fish, and the water tends to be clearer than the western Top End. Divers can expect hard and soft corals on reef slopes, gorgonians and sea whips in current-swept channels, and fish life including coral trout, cod, sweetlips, trevally, queenfish and mackerel, with turtles, reef sharks and rays. Manta rays and occasionally whale sharks are reported in Gove waters.

The appeal of a Wigram Island trip is remoteness and the chance to dive reefs that very few people have seen. The drawbacks are the long boat run, variable conditions in the trade-wind season, crocodiles, stingers and total self-reliance – the nearest chamber is in Darwin by aeromedical evacuation.

It suits experienced, self-sufficient divers on an organised expedition with a local skipper. Planning should include contingency days for weather, since the trade wind can pin boats in island anchorages for several days at a time, and all food, water and fuel must be carried from Nhulunbuy.

Wigram Island lies in the English Company's Islands north-west of Gove. The Marine Life Network notes that Gove operators have organised trips to offshore islands and reefs with camping on Wigram Island. Access is by boat from the Gove Boat Club ramp – a long run requiring a seaworthy vessel, full self-sufficiency and permits to camp on Yolŋu land.

Check with the Northern Land Council and Dhimurru before planning.

The Gove Peninsula sits at the north-west corner of the Gulf of Carpentaria, and tidal ranges here are much smaller than at Darwin (roughly 2–3 m), so diving is less tide-bound – but slack water still matters at channel and point sites. From April to September the south-east trade wind blows hard (often 15–25 knots), making the exposed east-facing coast and offshore islands rough by late morning; early starts and sites in the lee of islands are the norm. The build-up and early wet (October–December) bring glassy calm days and the best visibility.

In the wet season (December–March) the Gulf side is often still diveable, but inshore sites lose visibility after rain, cyclones are possible and box jellyfish are present.

Dive the reefs in the lee of the island at slack water, anchoring in sand and following reef edges at 8–15 m; drift dive channels between islands only with a live boat and SMBs.

Gove Diving & Fishing Charters (Nhulunbuy, ph 08 8987 3445) has provided air fills, gear hire, courses and boat trips to the offshore islands; confirm current operation before travelling. Otherwise private boats from the Gove Boat Club ramp, and local residents' informal dive groups.
