The old quarry on the Sydney Olympic Park site acted as a brick manufacturing plant from 1910 till 1988. Today it is full of water, and home to many waterbirds (and an endangered frog). An 18 metre high circular walkway runs above it, giving a bird’s-eye-view of the birds below. The floating green weed makes for interesting photography.
