With no trunk and at that location it is almost certain to be X. concava, but I'm not willing to confirm it. They're a nasty group to ID, even with the plant in the hand.

Thanks Jackie and BettyDon. I had no idea they were so tricky to i.d.

Xanthorrhoea australis has a definite trunk above ground. It is extraordinarily difficult to ID the species with underground trunks, even in flower and with the bracts around the flowers and between the flowers intact. One of the characters in the Plantnet key is th relative length of flower stalk and flower spike.

Which means that a whole of plant shot showing whether there is a trunk or not and the stalk/spike length is a good thing, though still doesn't guarantee you an ID. Habitat may also be useful eg if it is in heath, especially if poorly drained, it is likely to be resinosa. X. australis is more likely in elevated, rocky sites (but not invariably).
