Although it keys out as Opuntia elate on Plantnet - the lack of spines and finely and regularly spaced pits and teh reddish colour of teh hairs suggests blind cactus, so named as the fine easily separated hairs can blind cattle. This looks like a planted specimen - what were they thinking?
I'd say it was planted also. Not the first time I've seen similar plants deliberately planted outside of a suburban yard. I dug up all the ones I found along the verge of Kingsford-Smith Drive in Hawker some years ago.
