4:3 full steam machine or your will freeze your totally nutz off
You will be an ice machine from NT, but its not that cold, the NW wind can be like 14 -15 degree days with a little wind chill factor. but the SW to South stuff is cold and super wind chill. Start training now in the local supermarket freezer

but we love that time of year, big fronts and lots of wind, gusty as all, the local rule here is "Bring all your gear all the time" even when we go local it can be predicted 30 knots and go 15 or predicted no wind so you leave your gear and bring a surf board and it blows.
If you are staying for a little bit of time you will easy get some wind but don't leave that small kite behind. generally frontal winds requires 7 - 9m depowering kites depending on your weight.
Then again it might not happen if it shifts into slow winter start?
check www.southcentralkiteboarders.com and www.saksa.com.au for local spots
go into Onboard at Glenelg and they will point you too.
