Jas N Caz, we arrived on the Thursday morning before the Friday game and had a couple of hours sleep in the afternoon. We then stayed up until about midnight, so that we ensured that we had a good nights sleep and were up bright and early the next morning. This certainly ensured that we didn't suffer too bad with the jetlag.
If you arrive early enough on Friday then I'm sure that you too could grab a crafty couple of hours sleep. (make sure it's no longer, as you'll sleep through and be up all night!)
Good luck with your journey and I hope that you love Adelaide as much as we do, when you get here.
