OK - I will kick this one off with some of the very basics of landbased bait fishing, not necessarily specific to Moreton Bay, but general tips that apply to any landbased fishing. Maybe others can add on with specific tips that work for them in the bay. These are things I apply to my landbased fishing trips, especially when fishing new areas (new to me).
It helps to have a target species, or group of species with similar feeding habits.
Its best if you can find structure - this can be anything from close reefs, isolated coffee rock, weed beds, drop offs, jetties/pontoons, drains off flats, mouths of creeks canals, rock walls, rockky headlands, gutters on beaches, tidal contour lines on sand flats, deep holes close to shore. A good way to do this is to visit your intended spot at the bottom of the low tide and look - noting the structure in location to landmarks above water (it may not be visible at higher tides).
Make sure your bait is either live or very fresh (and dont leave it sitting in the sun to go off during the fishing session).
Present your bait on the hook so that it looks natural if its a dead bait, and if its a live bait so that it swims (fish,prawn,yabby) or wriggles (worms). Only use enough weight (lead/sinker) to keep the bait in the strike zone - you dont want it anchored to one spot (this usually only produces vermin).
Most - not all - landbased spots produce better/more fish during the low light periods. Dawn, Dusk and night. I often arrive as people are packing up to go home, and vice versa. Their catch rate is generally not that flash. Remember we are talking about how to catch a feed of fish - not how to wet a line and enjoy the surrounds (though your are going to be doing that anyway).
Fish as light as you can....i would rather loose an unstopable because I was fishing too light, than not get any bites because the line was way to heavy. For most of my bay type landbased fishing i use 3-4kg mono (we are talking bait fishing here - not lures - that is a topic for a whole new thread). I usually use 12 - 14lb leaders. If i keep getting bitten off it usually means the tailor are around so i might up the leader to 20lb, but only if i keep getting bitten off.
Keep the rod in your hand when fishing. I usually take a sand spike with me, but this is for keeping the reel out of the sand/dirt while i am rebaiting/rerigging (and prevents the rod being accidentally stepped on - especially at night). I only ever use one rod when landbased fishing. It is also usually not necessary to try to cast as far as you can, more often than not the fish are in close near the structure, not out in the desert. Accuracy is more important than distance (with accuracy will come increased distance)...especially at night.
My preferred outfits for the bay type landbased fishing spots are a 8'-10' rod with a multi taper softish action ( favourite outfit is a Wilson Shoreline matched with either a 5" Alvey or 3500 size threadline/spinning reel - I have both setups).
These are some of the basic tips. Now over to the bay gurus for more species specific tips on baits, techniques, general locations (as in what to fish for in what kind of location).
As I was once told during my business training....if you dont have a target you will never hit it.
