Where in Aussie are you mate? Might help with the 'safer spots' question

If you've had a few lessons, if you are cautious, ask and get to know the local crew, and they will let you know and it will help you learn what conditions are and aren't suitable.
It's just about being careful and cautions and not being stupid about going out in gusty or conditions you aren't ready for.
If you're in Qld area or Cairns, head to the cable park, and get some board practice in if you want to improve you board skills
