At this stage (with no flowers, no fruits), Alisma plantago-aquatica is virtually indistinguishable from Damasonium minus (both in same family), and there is no visual evidence as to what species this is.

However, it is very likely that this is Alisma plantago-aquatica. This species has been occasionally recorded in some years (depending on seasonal conditions) in seasonally or intermittently or occasionally wet places (drainage lines, streams, edges of wetlands and rivers) in the ACT whereas Damasonium minus has not: it seems to have a lower altitude / slighter warmer climate distribution pattern.
So, based on distribution patterns, and occurrence in other ACT grassland reserves, I consider this is Alisma plantago-aquatica.

And yes, it would be good to have a photo once the plant has flowered and fruiting. For that, best to focus on the fruits (the flowers are tiny and a bit challenging). Common name for Damasonium minus is 'Starfruit' and Sighting 4555224 shows why.

It is good to see this species turning up in grassland nature parks.
