Andy Murray continued his unbeaten singles start to 2015 by dispatching Marinko Matosevic in straight sets as Great Britain ended their Hopman Cup campaign with a whitewash victory over Australia in Perth.
The British No.1 won 6-3 6-2 after Heather Watson defeated Casey Dellacqua, to hand GB an unassailable lead heading into the final mixed doubles rubber.
Murray and Watson then teamed up to crush Dellacqua and Matosevic 7-5 6-1 to confirm a 3-0 win over the hosts to end the week in ideal fashion.
Despite winning two of their three group matches, Britain have missed out on a place in the weekend's final, with Poland set to face United States, but both Murray and Watson emerge from the first tour event of the year with much credit.
Murray won the World Tennis Championships in Abu Dhabi last week and goes into the year's first grand slam at the Australia Open in fine form after a lacklustre 2014 season.
After overcoming world No.29 Dellacqua 6-3 6-4, Watson heads to the Hobart International as she continues her preparation for the opening major of 2015.
"I knew that Casey's the home girl here and there was a lot of support here, but I have to thank everyone for cheering for me too," Watson said.
"It was so much fun. Casey played an amazing match and especially at the end it was pretty exciting."
Meanwhile, Great Britain will face Ukraine, Turkey and Liechtenstein in their Euro/Africa Zone Fed Cup group in February as they attempt to qualify for World Group II.
The team of Heather Watson, Johanna Konta, Anna Smith and Jocelyn Rae will travel to Budapest for the matches, which could end with a play-off against the winners of the other group which features Victoria Azarenka's Belarus.
