List of seaweeds and marine flowering plants of Australia (temperate waters)

The list of seaweeds and marine flowering plants of Australia (temperate waters) is a list of marine species that form a part of the flora of Australia.

The geographical range is from Perth, Western Australia to New South Wales, and those tropical species which are also found in this range may also be listed here.

The listed organisms are generally identifiable to the naked eye. Many microscopic algae also inhabit this region.

Ranges are generally given relating to Australian waters. If listed as endemic, they have been found only in the listed range. Others may have much greater ranges.
