Minerva Reef lies just off the eastern end of Dutton Way on Portland's wild Discovery Coast, a shallow limestone reef system reaching 3–5 metres depth. Popular with beginner shore divers and snorkelers, the site is best known for fossilised shark teeth that can be found scattered across the sandy pockets between coral and kelp. The easy shore access and sheltered inshore position make it a safe introduction to Victoria's cool-temperate waters, while the surrounding reef structure attracts schools of local reef fish. A white dive flag must be displayed when snorkelling or diving here.

Low risk: Fishing activity
The area is popular with anglers; active fishing lines and discarded hooks/tackle pose a snagging risk.
Low risk: Cool water temperatures
Southern Ocean waters can be cold year-round; prolonged exposure risks hypothermia without proper wetsuit.
Low risk: Kelp entanglement
Dense kelp growth in the shallows can entangle snorkellers; take care when entering and exiting.
