Not sure about this one. All leaves appear to be pinnate, in whorls of 6, which suggests M. aquifolium, but the pinnate segments are in 12 pairs which suggests M. cripsatum. As this is a major weed would appreciate another opinion.

The Vicflora key says that M. aquaticum has pectinate leaves (segments arranged like the teeth of a comb). Unfortunately with that key I cannot ID it to anything sensible.

Hi Michael
The Vicflora key is best for aquatics like this: https://vicflora.rbg.vic.gov.au/flora/key/2418
It keys out to a native Myriophllyum because:
Not glaucous
Less than 18 pinnae

Parrot’s feather is distinctively blue-green and pinnae are crowded and thus feather like in appearance.
