That's a very difficult question Mr PigWig, the other two replies are your best bet.
You want something, uncrowned and comfortable, as Leashy says high tide adds ease and comfort. I would forget any of the points until you are proficient.
Depending where you are on the Sunshine Coast there are plenty of uncrowned beach breaks, try the Kawana stretch, Maroochy North Shore, North of Coolum and around Peregian. These are all affected by wind at times, so pick your time and place and have fun.
