Hey Kate
Sandgate and brighton are pretty good spots for beginners and there is just about always someone else there to give you a hand if ya need it.
At low tide most of the areas in that area are a pain because it feels like kilometre out[: just to get to the water
and you gotta look out for the sandbanks they creep up on you
Happy kiting might even see you there one day im on a yellow Starkites kite (as shown in my profile picture
Cya then
