We use size 4 snapper leads. We did use size 4 star sinkers but got caught up on the reef a lot. Size 4 or 5 is more than wnough as you don't need to cast out very far and we find most fish are close the edge.

I fished False Entrance cliffs for years....don't go there anymore though.  We exclusively used 6 ounce snapper leads.  Make your rigs simple, as many of them do one way trips, especially when we targetted Baldies in close to the cliff.  Nowadays, with beefier rods, we use 8 ounce snapper leads.

I have size 4 but was worried it wouldn't be enough.....how much do size 4 weigh?

 Size 4 will be fine. You'll either be on to a fish/have ya bait snaffled within a minute or two... or you would have caught terrafirma and have donated a rig to the ocean's tackle box.

4-6oz on paternoster rig.

My last trip I switched to using bean sinkers (size 6?) which are about 2oz on a running rig.  Much prefer this method now.  

 Used to burn thru the lead both big and small sizes at steep.

Tried all sorts of rigs and sizes of leads and used to get good fish but also lost a LOT of lead.

got some advise on this web site to just to use a very simple rig and have never looked back and no longer loose anywhere near as much gear as I used to....and my catch rate hasn't dropped at all.

just 6ft of 60-80lb leader, single hook on the end with a med ball running sinker immediately above the hook.  No swivels no fancy set ups.

Sounds too simple to work but trick is not to use it as a running rig ie let it hit bottom but then keep the drag up full and the line tight at all times. Keeping the line tight stops you getting buried in the reef by even small fish (just keep your rod in hand and not just sitting around unattended). With this rig if you do get snagged in the reef, if you have kept the line tight and you continue to keep tight, all you need to do is vigorously bounce your rod tip and you'll bounce the sinker against the hook and you dislodge it out of the snag....

simple actually works best....sometimes.

 I've used large nuts or bolts, spark plugs or what ever else, run a light line to it so when it snags or a fish takes it, the line easily breaks and your free to retrieve the line.

I went to dirk last year with a mate of mine (gyprock 101 on here) and a good trick they taught me was if you do get snagged, don't snap it off straight away, quite often you'd wait and get another bite and they'd desnag you.

But who am I kidding no matter what you do prepare to lose some lead

 Just came back from Dirk , same type of fishing as steep , both worked a treat . Used bean and ball sinkers....and a lot of them.....and patience when jagged as it was normally a fish which buried us so let a bit of line out and waited for it to come back out.

 I use spark plugs on a sacrificial mono so don't care if I lose it. the spark plugs weigh only 45gm but it's easy enough to make a mold and add more lead. I figure if the fish aren't biting I can run a wire to the plug and electrocute them.

 I guess it's all personal preference. In my experience heavyer is better.. The times you get snagged most is when your rig is moving. To light and the swell will move your rig in and snag up. I use 8oz snapper, cast and leave it in the one position if no bite or time for bait change just wind like hell. Fishing cliffs you will always loose a few but this is my technique nowadays..

Belly

 Yep, Exactly the same as Belly, though not fished steep or quobba, have been doing more and more around Kalbarri and down south. 8oz holds bottom fine and then retrieve with the rod held high if necessary.

 We use 4-5 oz bean and 6 oz balls. running sinker rig, single hook depending on swell ,spot you are fishing..we pulled some fish with barotrauma so it can be deep in spots straight from shore. Star for beach not for reef,will loose them all the time.depends what you are chasing but that was suitable for baldies ( we caught 10 lb ers off cliff) big gts and big pinks .less snags as sinker bumps you off the reefs/rocks. Most snags due to fish taking you in it hole, pretty much cast and bite straight away.as mentioned above, wait for fish to get  out of hole or another one to come along and free you up rather than bust off.you will go through a lot of sinkers though ...Gyprock has pretty much nailed best way to go up there.

its different fishing to kalbarri and down Sth , I fish a lot  around kalbarri  ( have a house there )and wagoe , no comparison fishing style wise.where about you located , can lend you moulds for sinkers if you like , show you rigs we used.

How different we do things to still achieve the same goal. My experience up on the cliffs are limited, but when BB you loose stacks off lead (in some places would love to know what the bottom look like - might be a good spot for a lead recycling mine). Like some above have mentioned soon tired off retying rigs and just settled on the simplest rig possible, and that is ChrisGs above. First time we went up didnt have any many bean or ball sinkers, having thought snapper and stars was the go. Stars were as mentioned crap there, snappers in 4-6 OK but subsequent visits we had lots  of ball and beans on simple running rigs.

Cheers guys. Rig wise I was going to go with a simple dropper to a snapper sinker below with a swivel at the top. If I'm finding I'm busting off a bit I will try the running ball sinker option. Appreciate the help.
