I am guessing you are north of the river. Why don't you try Floreat drain to start with. Just fish to the right of the where the drain enters into the water. Best times to fish are around sunrise and sunset.
Try a surf paternoster rig. It will cover most of your target fish.
The sinker will depend on the conditions. If it is windy and there is a bit if a swell it is best to use a star sinker. If it is reasonably calm try a spoon sinker.
Try mulies on a set of gangs to start with and you might have some luck with a tailor,

Im actually south of the river. Jandakot to be exact.

Im following my sister's boyfriend to North Mole tommorow, can I use the rod there or is it too big?

Thanks 

you might find some good reads of previous posts hope this was some help cheers and good luck...

It will certainly help if you catch a good fish and you want to try and keep your catch away from the rocks.
I can't help you too much with south of the river beach fishing spots. But as wayno said, there are heaps of posts on beach fishing on the site.

if you want to travel abit further south try challenger beach in kwinana for tailor, i use a 13ft and i fish any beach around perth plus north mole south mole and in the river for mulloway at nite. my theory is if you can cast it at a spot use it lol. its hit and miss most places in perth but if you get the right time itll be worth it

I'll try it a North Mole and see what the results are. Do I use the Paternoster rig at North Mole? Quite a bit of rocks there.

use gangs of 3 and you will get taylor if they are still hanging around at sunset and sun rise and north mole good for snapper in winter and skippy herring after winter try down at the kwinna grain terminal salmon trout around atm hope that helps mate good luck

mulie on gangs if you are fishing on the north side of North Mole, or a rig with a running sinker.
Otherwise, go the paternoster. You should be able to cast well away from the rocks - and with the 12 footer you should be able to lift your rig up easy without getting snagged.

I'll test it out. Never use a 12 footer before always used 7" 

Catch was poor, only 2 tailors(35-37cm), snook and a yellow tail. Quite hard to get the full potential of the rod when its quite hard to cast with rocks around. Probably it wasn't a good time.

I'm gonna try catch metro tailor, anybody know where is a good spot. Never caught them before, always getting chopper tailors.

Thanks 

at the moment Gareth. 35 to 37 cm isn't too bad.

next time your down at the mole try using a burley cage with a trace about 1mtr long. as you said it is hard to get the full use of a rod down there but with a shorter trace you can give it a bit more , using the burlet you can get a wide range of fish that will take the bait. on the surface you can get using a small set of gangs with either white bait or bluebait, herring and tailor , if you let your bait sink you can get some good size skippy there as well .if you are just after herring or gardies try using the same setup but using small hooks with either shelled pieces of prawn or maggots. just remember keep the line tightish so you can feel the bites and make your burley a bit firmer so it will stay in the cage a bit longer

im just trying to catch something big and enjoyable. ive had my share of catching bull herrings and smallish fish on my lil 6 ft rod. Now im setting the bar higher. Btw which part of North Mole. I dont go to the part where most people fish(light house area) usually go to the rocks facing South Mole.
