Collected for further identification. After observing a female guarding her egg sac in my front yard for months (https://canberra.naturemapr.org/Community/Sightings/Details/3377790) and the subsequent emergence of spiderlings (https://canberra.naturemapr.org/Community/Sightings/Details/3380925 - still to be confirmed by moderator) I am confident of my identification.
