Hi Odille,
Welcome - in advance - to Tas!
I'm helping organise the photography for the Tall Ships. Another couple local guys and I also did similar for the Wooden Boats and ANZAC Day. IANAM (I am not a member), but doing this through the Hobart Photographic Society so we get a significant number of people volunteering, and develop skills of that club.
Basically, for these three events we've organised around 15 people plus ourselves, to volunteer to do the photography for the events. The photographers retain copyright, but the organisation can also use them (with agreement, attribution, ...). The big advantage is that for the Tall Ships, volunteers get free access to the ships, while the general public has to pay. We're organising things at the moment, including a practice photojournalism session on 31/8 too.
First step is to volunteer on the AWBF/TS web site, and you can specify days/sessions you're available for.
If you're interested let me know and we can arrange more.
Oh, and I'll be there all 6 days rather than just occasional meetups
