Veronica Island is one of the offshore islands dived from Gove. The Marine Life Network records a depth range of about 7–30 m and notes that the best diving is on the island's sea walls, which are patrolled by pelagic fish.

The walls carry soft corals, gorgonians and sea whips, giving colour and structure in the moderate currents that sweep past the island. Trevally, mackerel, queenfish and other pelagics cruise along the face, and reef sharks and turtles are likely. Veronica is also noted for its smaller reef life – flatworms, sea stars, crabs and molluscs – which makes it a good choice for macro enthusiasts who slow down and look closely along the wall.

As with other Gove sites, clarity is better than in the western Top End because the Gulf of Carpentaria has smaller tides and less river outflow, and coral life is richer in shallower water. Conditions are driven by the south-east trade wind, so the island is best dived early on calm days or during the build-up.

Very little additional detail has been published about Veronica Island, and it is visited mainly by local divers with boats. It suits advanced divers comfortable with wall diving in open water and anyone who enjoys finding small invertebrates as much as watching fish. Permits are required for Yolŋu land and sea country access, and landing on the island should not be assumed. Combining it with Bromby or Bremer Island on a two-dive day is the usual way local divers make the most of a calm window.

From Nhulunbuy, launch at the Gove Boat Club ramp in Melville Bay and run to Veronica Island with a local skipper – the island's position is not given in published dive guides. Go early in the day in trade-wind season. Anchor in sand in the lee or drift the walls with a live boat, depending on current.

Nhulunbuy itself is reached by daily flights from Darwin (about 1 hour 10 minutes) and Cairns, or by the Central Arnhem Road in the dry season with an NLC permit.

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.

Drop onto the sea wall, descend to 18–25 m and follow the wall with it on one shoulder, looking both at the invertebrates on the face and out into the blue for pelagics. Ascend gradually up the wall to finish in the shallows at 5 m.

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.
