Lucky Bay is one of the most unique remote flat water spot I've kited. Definitely beginner friendly as long as you don't go face first into the reef. It's not super wide but wide enough to enjoy some nice butter flat water tacks.
Access is a bit of a mission and you will need a proper 4x4 with tyres down to drive up and down some dunes in soft sand but that's what makes it extra special I guess.
Looks like you might get some pretty light breezes over the weekend, hopefully you have a big kite and a big board otherwise I don't think you will kite much unless the forecast changes.
