id love to know how to target jewies and snapper off the land
They're easy - if you can catch yellowtail there, and there's deepish water nearby and plenty structure (jewfish are ambush predators and they stalk their prey) , somewhere near a wharf, or gutter or a channel, or a bridge are always likely jew haunts.
When I'm seriously targeting jew I use the same rod and reel as above, only I swap over the spools to the one loaded up with high quality 40 lb mono (I use a 65 lb shock trace) and I up the hook size to 8/0 and 10/0s (extra strong, and I SHARPEN THE HOOKS TO RAZER SHARP), one hook for a livebait (yellowtail, chopper tailor, mullet or snall trevally) through the tail on top but not breaking the spine (8/0 or 10/0 depending on size of livebaits) or 2 x 8/0 XXS SS Suicides (top on sliding snood) if I'm using a slab / whole fillet of fish or whole squid (I catch my own squid and freeze them in individual bags just for this).
Then it's a matter of getting the bait far enough from the rocks to avoid hang ups and snags and to be found by any jew who happens to be nearby or cruising by - livebaits are best , they attract the jew by swimming on the hook and struggling and they panic if a jew is about. Dead baits rely on the smelling / tasting the bait. Dead baits - if it's not fresh enough for you to eat it , don't offer it to the jewfish.
Bigger sinkers too. (I go to 6oz and 8oz snapper leads and they have to free running !, size depends on the current and size of the bait you want to keep on the bottom.
Have fished for jew using floats (big chunks of foam) successfully too, but there are so many lobster pots around the ends of and along the breakwaters now that it's impossible to use the float method and follow the float along the walls from the cast out like we used to in the 70s and 80s.
The rest is investing time - jewfish are not as plentiful as they used to be - used to be able able to catch at least one jewy a trip, often several if the school jew came through or the jew were spawning. Now you more often go home fishless (and consider yourself lucky if you had a good run or two).
Most jewfish are lost in the first few seconds - over zealous / impatient / inexperienced fisho try to set the hook too soon and the bait gets dropped or spat out. Gotta let them run at least twice..
In summer I often fish all day for snapper, then an hour or 2 before dark I'll put water in the tank and I'll breal out the little flick stick and catch yellowtail run under my set rods (usually 2 when I'm fishing for snapper), as the sets I'll reel in the snapper gear, swap over one of the spools ,rig for jewfish, and lob out a livebait then I'll make myself comfy and wait .... and wait .... and wait , reeling in the livebait when I think its cramped up or died (usually change live baits every 30 mins or so) , been known to fish all night if I'm getting runs or even better catching the occasional jewfish.
My best nght ever I got 8 jewfish between 15 lb and 35 lb. and I had to leave them biting as I ran out of live baits and had recycled the dead livebaits as fillet baits. My best jewfish ever was a monster weighing in at 86 lb and I believe hold the record for the biggest jewfish in living memory from Nobbys Wall. (I've caught about a dozen over 60 lb there, and on Stockton Wall, and from the Dykes at Carrington and one of them came from the rocks near the Newcastle Harbour Pilot Station. ALL my biggest jew took livebaits.
