Luke McCullochGuestGary JubelinHostWell, the, the majority of the work, just breaking it up roughly in, in percentage of it, body recovery, would, would that be the, the primary, primary role as a police diver?
With what I'd done in my time, I reckon it was about 50%, um, that with, with weapons, drugs, um, car recoveries, vessel recoveries, bodies, body probably 50% of the time, yeah.

Like, it was just a, a le- a pool that had been left for clearly, you know, a decade, I reckon.

It was bloody thick as anything and, um, and there was just tree leaves everywhere, like gum leaves.
But then as I was trailing back, so I went shallow end down to deep end, turned around, scaled again, came back up from the deep end back to the shallow side, and I remember getting to the staircase and going like, come on, surely if, 'cause the body was next to the staircase.
