The Yarra Estuary on the Port Melbourne side of the river is a good spot to take the kids fishing.
Generally, I stick to the embankment just to the north and below the Westgate bridge. There’s a channel to cast out into for deeper water. Be careful of snags as the Yarra River estuary here contains quite a few rocky snags at and below the drop-off to the shipping channel.
Flathead, bream and mullet are the target species for many fishos here. Pinky snapper is also amongst the more common catches here.
For those up to the challenge, the prized mulloway does frequent the Yarra Estuary right up to Richmond.
