Day 2 (18 January) The second day saw both Nadal and Murray win when their opponents retired. There was also a win for wildcard Bernard Tomic whilst Baghdatis had to go to five sets before sealing victory, while Del Potro came through his first Grand Slam match since injury in straight sets. Both Tsonga and Verdasco came from two sets down to move into the next round. On the women's side both Molik and Radwańska won marathon final sets to advance into the second round. There was also a win for home hope Sam Stosur and world number two Vera Zvonerva. While the 2008 finalist Ana Ivanovic crashed out 10–8 in the final set.

In the evening matches on Rod Laver could not have been more different. The first match was a battle between two former number ones, Kim Clijsters and Dinara Safina. Clijsters did not lose a game in the forty five minutes they spent on court. The men's evening match on Laver was a repeat of the 2002 Wimbledon final between home hope Lleyton Hewitt and Argentine David Nalbandian. The pair traded breaks and shared the first four sets. Nalbandian got an early break in the deciding set. At 5–4 the Argentine served for the match, and Hewitt just as he did in the fourth set broke Nalbandian as he served for the set. At 5–6 Hewitt had two match points which Nalbandian saved, only for the Argentine to force Hewitt to save break points in the next game. At seven all the Argentine broke to love and held on to serve the match out for a 3–6 6–4 3–6 7–6(1) 9–7, win at seven minutes past one in the morning after close to a five hours battle.

Day 7 (23 January) History was created in the match between Kuznetsova and Schiavone. The match became the longest match, in terms of time for women in a Grand Slam as it lasted for 4 hours, and 44 minutes. At 8–7 in the final set Kuznetsova had three match points, but the Italian saved all three. In the next game Schiavone broke her opponents serve but touched the net after hitting the winner, meaning the point went to Kuznetsova, when holding three break points. Kuznetsova had another three match points in the next game before a run of four games in a row where the serve was broken. Finally after breaking in the previous game and missing three match points Schiavone closed the match out to win 16–14 in the final set.
