Day 12 of the Australian Open starts with Serena and Venus Williams taking on Cara Black and Liezel Huber in the final of the women's doubles
The Williams sisters, the defending champions, are all smiles after collecting their fourth Australian doubles title and 11th together in Grand Slams with a 6-4 6-3 victory
Britain's Laura Robson is also in action, taking on Kristyna Pliskova of the Czech Republic for a place in the final of the junior singles
Robson, 16, is in supreme form as she cruises to a 6-3 6-1 victory in 65 minutes and will play Pliskova's twin sister Karolina in Saturday's final
Another British star, Peter Norfolk, also progressed - reaching the final of the Quad Wheelchair singles by beating Sweden's Johan Andersson 6-1 6-2
Andy Murray booked his place in the men's final on Thursday but the Scot is back at Melbourne Park for a practice session
Murray, who will meet the winner of Friday's semi-final between Roger Federer and Jo-Wilfried Tsonga, cuts a relaxed figure in training
It is Federer - the world number one - who makes the brighter start against the Frenchman, breaking Tsonga twice to easily wrap up the first set
Tsonga, a losing finalist in Melbourne in 2008, cannot find any response in the second set and looks short of form and confidence as Federer moves into a two-set lead in just over an hour
There is no way back for the Frenchman, and Federer swiftly moves into his 22nd Grand Slam final after completing a 6-2 6-3 6-2 victory in just 88 minutes
Federer will face Murray on Sunday looking to secure his 16th Grand Slam title and his fourth in Australia by winning a title he last secured in 2007
