Probably Pelican Point for a newbie as it is shallow at both ends on an Easterly if you don't go too far before turning. Finding a car spot in the carpark can be a hassle during uni term though. Point Walter is good on an easterly but it gets deep quickly, even close to the shore there is a deep channel you can't stand up in. The kiter's beach at Point Walter (closer to Attadale) is shallow a bit further out, but can often be too shallow for a bigger fin.
