Slinky got it right, the best rig for the surf is the paternoster with either a single or double dropper.
Use either a snapper lead, star sinker or beach sinker on the end and keep your droppers about 30cm apart.
I normally throw a double with a mullet strip on each or a single with a whole pillie. Sometimes you can use a whole small squid on each or beachworms. Very versatile. You can even throw two different baits.
My reccommendation is to use a quality ball bearing swivel above the rig.
