While the water is a touch murky, Westernport Bay is still producing some mega Squid; both up along the Northern banks and also down South around Flinders.  The southern section of the bay is probably a slightly higher chance at the minute with better water clarity.  Good customer Bob went out and had a fish around Somers, and found some thumpers like this 48cm hood length ripper.  Size 3.5 Shimano Keimuras were his jig of choice.
