Last French Australian Open winner

Question

Jo-Wilfried Tsonga is in the semi-finals of the Australian Open 2010 and potentially two wins away from the title. So when was the last French Champion at the Australian Grand Slam. In the women’s singles, it was Amelie Mauresmo but in the men’s we need to go back much, much further. As far as 1928 in fact, when Jean Borotra won the title back when the tournament was known as the Australian Championships.
