Old Man's Hat, near Sydney, is an exposed offshore pinnacle that offers a dynamic dive. We often find schooling kingfish and yellowtail there, circling the rock structure. The site can get surgey, particularly with easterly swells, making it best for confident divers comfortable with a bit of movement. It's a good spot for a boat dive when the conditions align.
