Hi, at the moment there are restrictions on where you can kite around Goolwa and the Murray. -
www.sa.gov.au/topics/emergencies-and-safety/river-murray-flood/declaration-and-directionBasically you can't kite at Sugars Beach (on Hindmarsh Island) or around the mouth of the river at Goolwa. It's pretty grim at the moment, apparently dead roos are getting washed out

You're OK further west towards Middleton (for waves) and Victor Harbor (Kent Reserve) for flatter water.
There's also Boggy Lake (sounds inviting, eh?

) I haven't kited it but it's meant to be super flat but can be popular with wind surfers when it's on.
