Bretto74: Not sure if you were serious or not. But how do you get that Kurnell would be working in a southerly? It's straight offshore, not recommended for anyone, regardless of level (plus wind comes over land = gusty). Check the map:

Or any other beach on the map where you're allowed to kite and which is south or south east facing.
Also, if you can't stay upwind make sure you walk upwind of any obstacles, open water area etc. before you start so you have a good bit of distance to drift before anything bad happens. I saw a guy getting in the water only 10m upwind of a rock groin the other day, ended up almost getting smashed on the rocks. So make sure to walk upwind first.
