lleyton hewitt s sister

Hes one of the players on the tour that I expected to do well. But what happened to him? The last time Ive seen him play was against Agassi during the Australian Open 2005. See, look at this pic:

Yes, thats hes girlfriend at the time who is Lleyton Hewitts sister. Seriously though, what has he been doing since then? I believe he was in Australia during Australian Open this year, unfortunately his match wasnt aired for me to observe. All I remember about his game is that hes able to hit huge serves, well thats actually an understatement! He is not able, but he HITS a lot of aces. But those precious lleyton hewitt s sister didnt lleyton hewitt s sister him win against Agassi. So, if anyone knows what hes been up to, would you mind telling me?
