Thanks Harvey, totally understand your reasoning. Too bad it was a female and not a male :) Thank you for your time and effort it is greatly appreciated.
It very likely is Pseudagrion aureofrons, and I note Jon Tann has IDed it as such on iNaturalist, but despite his ID reasoning I can't see sufficient diagnostic detail to be certain. Location-wise, it is a little unusual for this species - They are uncommon at best around Kellys Swamp / Jerrabomberra wetlands (but common along the Molonglo and edges of Lake Burley Griffin which aren't far away; and females may well wander seeking seclusion).
