Stockton is about 30kms long with waves, not for a beginer, but can be droped off at one end and picked up at the other, need a 4wd & permit anywhere in between.

If you do not have a 4wd the above two will only offer short runs with NE winds generally onshore.
Hawks nest - bay side, about 2 1/2 kms from winda woppa around the bay to the other end at jimmys beach
If you are learning and cannot go upwind you could start at either end and you would get to the middle with about a 1km run. This would only be in a SW to SE. If it is NE wind the only option is a boat or walk (about 800m)out to the end of Jimmys beach (or a 4wd & a medical certificate for a special permit), this will be offshore so if you cannot go upwind and have no boat you will very quickly need to be rescued . This is scattered with lots of other people this time of year enjoying the water including jetskis, boats anchored from the shore and snorklers.
