Huon reserve contains a cluster of approximately 70[citation needed] seamounts peaking 750 m (2,460 ft) to 1,700 m (5,600 ft) above the sea floor.

They appear as cone-shaped submerged mountains, which provide a range of depths for a diversity of plants and animals.

The reserve is a foraging area for great white sharks and seabirds and a spawning or nursery area for important commercial fish, including ocean perch and blue warehou.

[4] A majority of the Huon marine reserve area is IUCN protected area category VI and zoned as 'Multiple Use'.

A smaller section of 'Habitat Protection Zone' in the west of the reserve protects the unique and vulnerable benthic communities of the reserve's seamounts.
