This is lmost certainly a Cyperus species, but the individual spikeltes look really small, so i don't recognise the species from the photos - might be worth collecting a specimen if you are going past soon.

Thanks Russell.
I didn't recognise this one which has different seed-heads from those I know. It was hard to photograph because it was in the water and I couldn't get closer. With the recent rain it will be underwater now and may be damaged by the process. I will endeavour to get a specimen when I can, but it may not be until next growing season.

ID by David Albrecht at the Australian National Herbarium from supplied specimen.

Local nurseries stock this plant and recommend it for dam bank stabilisation so I guess it is just a matter of time before it became naturalised.

This species has been planted throughout the ACT in wetlands/ponds. It has persisted in Macgregor bio-retention ponds for 8+ years now.
