[4] It was elevated to species status by Maarten J. M. Christenhusz, based on phylogenetic analysis.

[9] Due to its wide range and variation, it is possible that some populations of Doodia australis may warrant description as distinct species or subspecies.

[10] Doodia australis is a fern covered in dense black scales.

It can be distinguished from other New Zealand members of Doodia due to the pinkish red colour of new fronds.

The species prefers coastal or lowland sites, and can sometimes become a weed in urban environments.
