Hi Zues,
I would definitely choose Pelican Pt if I were you. The water is flat and shallow and you will feel very safe in these surroundings. At the same time there is a lot of other windsurfers sailing there on windy days, so you'll get a lot of inspiration!

I reckon it is a really good idea to get some windsurfing lessons. It will help you improve really fast and you'll save a lot of hours or even days on the water repeating the same mistakes over and over again.
Try to contact Windforce (www.windforce.com.au) or go down to Pelican Pt where you will find Windforce's windsurfing school (wednesday to Sunday from 11am to 7pm). Here you'll be able to get lessons and maybe try out some of their new equipment.
Good luck

See you on the water!
Stephanie!
