It's a hard beach to figure out sometimes mate - a mark will fish one night, then not the next when the conditions are exactly the same. There are some popular shots: the Astley end, middle toilets, back of the farm/ranch, Meggies burn, the groynes, bandstand, Stubblies etc etc. but the only way to know where the fish are is get down & give it a chuck.
Probably the best advice I can give is don't stay in one spot if you haven't had a bite after 2 or 3 chucks..
move! The beach changes all the time depending on how the sea's been running, holes come & go and you need to find a spot where the fish are congregating. Also you don't often need to move far; I fished one night before xmas and in the first spot I tried there must have been a hole full of crab, your baits were stripped in five minutes. I moved no more than 50yds to the left and the crab disappeared but I got no bites, moved another 50yds and got 6 fish in 6 chucks.
Personally, I nearly always use a 2 hook clipped rig (loop rig) which can be used as a flapper as well; if I'm short of bait or using bigger lug & razor type baits I'll use a 1 hook clip down rig. Vary your casting distance as fish can be anywhere from 30yds to as far as you can throw your bait. For codlings, best fished with a good sea on, bigger tides are better (as there can be a strong tide rip, especially bad on the smaller tides when there's a sea running which can make it impossible to hold bottom).
Number one bait? lugworm, lugworm & more lugworm! Rag can also work (and might get you the odd bass if they're there and the conditions are right) and will get you flounders as well, often tipped with a bit of mackerel. This winter there have also been a lot of whiting around, which will take just about any of the above - certain baits seem to work better in different spots, so it pays to have a few to choose from. For codlings, as well as lug you can try razor, clam & crab - all will take fish.
Hope this helps,
