Amphibolis antarctica

The species is generally reported as occurring from Exmouth Gulf on the north-west coast of Western Australia, south along the west coast and east along the south coast as far as Wilsons Promontory in Victoria.^[8] However FloraBase reports an isolated specimen record from east of Port Hedland, over 500 kilometres (310 mi) north-east of Exmouth Gulf.^[5]

It occur primarily in the sublittoral zone, where it forms extensive meadows. It can occur as deep as 27 metres (89 ft), but does not often form meadows below 13 metres (43 ft). It can also grow in extremely shallow waters, with its leaves floating on the surface, although this often results in leaf damage and loss. The species tolerates a range of habitats. It has been found growing on a variety of substrates, including sand-covered rock, gravel, sand and clay. It grows in areas of both high and low water flow, and occurs in areas of very high salinity.^[8]
