Beroe australis is a species of beroid ctenophore, or comb jelly, found in the Pacific Ocean.

[1] B. australis was originally described by Alexander Agassiz and Alfred G. Mayer from a specimen caught off Fiji in December 1897.

[2] Subsequent studies have noted its similarity to Beroe forskalii, with some considering the two species synonymous.

Its body is compressed laterally, with one side being about three times as broad as the other.

The photocytes, which run the length of the comb rows and surround the statocyst, are crimson lake in color.
