I live at Umina and here are all different spots I kite....

Umina Beach - SSW to SE (NE is possible in the channel for the thrill seekers). Waves are not generally large, but a 200m ride is an acceptable replacement, helpful locals
Toowoon Bay - Only ever kited here in a NE, (it is very small)
Picnic Point (The Entrance) - SW to NW, super smooth and super shallow (think two inches), generally gusty
Canton Beach (Toukley) - SW (SE should work), quite smooth close to shore, super choppy 200m out (you can surf the chop on big days!!!)
Norah Head - NE to E, an ocean side spot that is protected (mostly) by a rock reef. Can get a nice swell travelling gap
Birdie Beach to Norah Head - NE (E to SE should work), excellent downwinder location, great waves, odd shark, dolphin, turtle
Caves Beach - NE to SE, great wave location
Swansea Channel (Salts) - NE, best flat water spot I have tried, really consistent summer breeze when it blows
Swansea Co-Op - SSW to W, a good flat water spot, super shallow, wear booties for the razor fish
Squids @ Belmont - NW to W, a good flat water spot, super shallow, wear booties for the razor fish
