You should be right St Paul, The Snapper would be around until atleast april. Just a streak of bad luck I suspect.
If you do move up to Blem it would open up a few more options fishing wise. You would still have the sharks on the east coast beaches like cloudy bay, Seaview, Marfells….. Although you might lose Elephant fish.
But the main advantage would be the ‘sounds’ and all of the ‘warmer water’ species. So Snapper and Kingfish would replace Elephant fish and Salmon.
