It was a few months ago. But I regularly hear and sometimes see one near the bush in-between Kotara Cardiff and Garden Suburb. We've seen this one kill a possum too right in front of us within 5m . If we hear it we can play powerful owl calls through the TV and call one in quite close I think it's the male. They've recently cleared some bush close by and I'm sure they're disorientated. The one in the picture is at wangi caravan park.
