from sidney, there was to be a 5 or 6 day surf school / bus that took you from sidney to byron bay (which you should not miss), while stopping here and there at little surf spots and spending a couple nights at there surf home base location.
Pretty enjoyable to spend a chunk of your time, particularly when food and accomodation is included with the price.

Pretty sure that's the one
once you get to byron, it's pretty easy to spend a few days there and easily get to surfers paradise for a couple more days.
