im ben, 21yo and new in this forum

in a couple of days starts my surftripp from brisbane to sydney. im a beginner, but determined to get as much practice as possible. i found a list of good spots:
* Duranbah/Rainbow Bay/Greenmount (Gold Coast, Queensland)
* Caloundra, Alexandra Headland (Sunshine Coast, Queensland)
* Byron Bay, Evans Head, Yamba, Scotts Head, South West Rocks (North NSW, recommended)
* Merewether Beach, Shelly Beach, Avoca Beach, Terrigal Beach, Copacobana Beach, North Narrabeen, Manly Beach, Bondi Beach (Central Coast NSW, HIGHLY recommendend!)
any other tipps?
how difficult is it to sell a beginner board in sydney, are there any shop who buy and sell occasion boards?
by the way, if have a van so if any one would like to join me for a while let me know.
