Fido's Reef lies a short boat ride off Point Danger, the headland that marks the NSW/Queensland border at Tweed Heads, and combines a naturally rugged rock reef with the scattered remains of a steamer that came to grief on this stretch of coast in the early twentieth century. The wreckage itself is broken and low-lying rather than an intact hull — mostly plate and structural fragments now bound into the reef by decades of coral and sponge growth — so this is best thought of as a reef dive with historical interest rather than a wreck dive in its own right. The rock structure rises and falls in a series of gutters and low walls between about 10 and 22 m, providing plenty of hiding places for turtles, wobbegong sharks and the Queensland groper that favour this section of coast.

Hard and soft corals and sponge growth are typical of the subtropical overlap zone here, where the East Australian Current keeps the water warm for most of the year and brings occasional tropical vagrant fish species well south of their usual range. Reef fish life is solid without being spectacular, and the site is more valued locally for its relative quiet compared with the far busier Cook Island a few kilometres north. Because Fido's Reef is close inshore it is subject to the same visibility problems as the rest of the Tweed coastline, clouding for several days after the river floods following heavy rain, and it is fully exposed to easterly and south-easterly swell, so a diveable day at Cook Island does not guarantee the same conditions here.

It is not marketed as a signature dive by any operator and detailed information on the wreck's identity, exact depths and GPS position is limited, so divers planning a trip here should confirm current conditions and site details directly with a Tweed Heads or Coolangatta dive operator before booking.

Boat access only. Launch at Jack Evans Boat Harbour or Boyds Bay on the Tweed River, or from Kirra/Coolangatta on the Queensland side, and run a short distance out from Point Danger.

The Tweed/Coolangatta coast is exposed to south-easterly and easterly swell year-round; charters generally want under 1.5 m swell and light winds. A strong East Australian Current push (common November–May) can add 1–2 knots of southerly drift on the outer reefs, turning some sites into serious drift dives. The Tweed River bar and river mouth are tide- and swell-dependent and can close to small boats in a big easterly swell.

Visibility on the inshore reefs drops for days after heavy rain flushes the Tweed River; the offshore reef and shark sites are less affected. Winter (June–September) gives the clearest, calmest water and the grey nurse shark season; summer is warmer with more current and better odds of leopard sharks and mantas.

Descend onto the rugged reef top, explore the scattered wreckage and rock gutters between 10 and 20 m, then shallow up for the safety stop over the reef.

No dedicated daily charter identified; visited occasionally by Tweed/Coolangatta operators and private boats alongside Cook Island and Kingscliff Reef trips.
