Can't help you on the depths and lures as we didn't hit anything of size either. maybe 45cm eyeball measurement on the largest. Weren't really trying that hard, was mostly out for prawning so just dropped one line down to kill the time, basically trolling were we could keep an eye on our bouys. I think deeper water out by Entrance is where you want to be to find the real fish, but I'm no winter chinook expert, just what I've gleaned from reading.
Either that was you we chatted with at the wash down around 2:30 or so, or some guy is going around using your "same fish" joke?
