Good to average in melbourne, plenty of southerly bay side seabreeze days, I counted around 10 days in row of over 15 knots in the beginning of feb, Check the port phillip bay bom report out for the bayside report, wind guru for anything north to southwest, wind willy and kite bom.
If there's not enough wind to go upwind or hold ground do a down winder, which can be more fun than kiting in one spot anyway.
