Hi mate, i was also at tunks at 5, we left in a white centre console and hit the bait grounds....didnt get any squid but landed a heap of yakkas.... none of the yakkas produced and kings so went in search for more squid. We scored one mumma squid and then searched the sounder for some likely spots..... My advice is this, dont rely on one spot, keep a close eye on your sounder and check out all the channel markers for likely activity, if you see something below, drop some baits, if they dont get smashed in 5 minutes MOVE. I find if you sit and burly you get too many pickers!!!
Try this technique next time - you may crack it!
We landed 4 kings this way all on fresh strip squid....No bigguns, just 67-70cm.
Attached is a pic of one of the kings today with my lovely daughter who greeted me with a "i dont like that big fish, any little ones?" God bless them!
