Boags Marine Park encompasses diverse soft sediment communities dominated by crustaceans, polychaete worms and molluscs. Such habitats are typical of the Bass Strait Shelf Province and seabed. Boags Marine Park also provides important foraging grounds for nearby breeding colonies of seabirds, and habitat for southern right and pygmy blue whales.

The park is located off the northwest tip of Tasmania, just north of Three Hummock Island and wholly within the Bass Strait. It covers 537 square kilometres and is a Multiple Use zone.Parks Australia

Boags ranges from less than 10 to 62 metres depth, with an average depth of 52 metres. The majority of the Park (>99%) falls within the mesophotic zone (30-70 metres). [View on map] The mapped areas of the seafloor are dominated by Plane (73%) and Apron (12%) geomorphology. [View on map]
