Hi Sonic1,
If you are heading to Port, you want to contact Bretto at Windswell. His school/retail is situated on the southern end of 4 mile beach.
The tropical wind will have about 20% less grunt than southern cooler wind in my experience. At 95 kegs you wont be using any small kites. You may get to have a run on the 11m but mostly I reckon you could just get away with the one 14m, in fact, check with Bretto, I think he rents kites, if so, I'd leave the 11m behind so you've got less to drag around with you.
Port haven't had a good season for several years, then again, neither have the rest of us

Check out www.windswell.com.au for all the latest and definately call Bretto as he has lived and worked in Port for longer than I have known him.
Good winds and have a great trip,
