Melbourne is famous for its tennis – but the summer action actually hits off in Sydney, with the United Cup. Now in its third year, this international mixed tennis tournament sees top male-female teams from all over the world hit it out in Sydney and Perth (with Sydney games on in Olympic Park). The fun thing about the United Cup is that these big-name players are relying on the success of their teammates, as well as themselves – it's a country-versus-country tennis tournament, as opposed to individual-versus-individual. So there's a team comaraderie on the sidelines that you don't get at the Grand Slams. And then there's the fact that the teams are made up of men and women – it's a genuinely mixed tennis tournament.
