Kite beach at Brighton is the usual local spot in a northerly. It's very good in NW. Gusty and horrible and slightly offshore in true N, but doable if you're competent and careful.

North of the pier looks quite nice on the map. I kited there 10 years or so ago and it was fun. The beach can be a bit narrow at high tide.
Legend has it that kiting is not permitted at Frankston to the S of the pier. It's quite close to the boat ramp, the road and I think it's infested with jet skiers.
