Great Britain were denied a place in the Hopman Cup final as Australia Green edged out France in a tense finish.
The British team of Andy Murray and Heather Watson had put pressure on Australia by beating Germany 3-0 in Perth.
That meant the Australian duo of Nick Kyrgios and Daria Gavrilova needed to beat France to secure their place in the final.
Kyrgios comfortably defeated Kenny De Schepper but Gavrilova lost to Caroline Garcia and the mixed doubles went to a deciding match tiebreak.
It was close all the way through but Gavrilova pulled off a brilliant volley to save a French match point at 9-8 and they won three points in a row to clinch victory.
Their 11-9 success was a repeat of the deciding tie-break they won against Britain on Wednesday, which ultimately proved the difference between the sides.
An Australian team will play in the Hopman Cup final for the first time in 13 years, with Kyrgios and Gavrilova set to take on the Ukrainian pairing of Alexandr Dolgopolov and Elina Svitolina.
Nevertheless, Murray and Watson's performance against Germany saw them finish the tournament on a positive note.
Watson had impressed in beating Gavrilova on Wednesday and claimed a notable scalp with a 6-3 6-4 win over former Wimbledon finalist Sabine Lisicki.
The British No.2 made the decisive break at 4-3 in the first set before serving it out to 15. The second set was more comfortable for Watson, who broke twice to seal the rubber.
Murray then held his part of the bargain, seeing off highly-rated teenager Alexander Zverev 6-3 6-4. The only worrying moments for the world No.2 came at the end of the second set as, after leading 5-2, he allowed Zverev a sniff of 5-5.
But he fought off the danger and the British pair went on to win the mixed doubles by the same 6-3 6-4 scoreline.
After the win, Murray said: "I moved a bit better today, I hit the ball a little bit cleaner from the back of the court, which was good. "Not so much maybe at the end of the match, a few sloppy points in the 5-2 game and then obviously when it's 5-4 then you want to finish the match and there are a few nerves, so I should have done a little bit better there, but the rest of the match was decent." Watson, meanwhile, was happy to get some court time ahead of her defence of the Hobart International and the Australian Open.
"I always love the beginning of the year here in Australia," she said. "Sometimes it just takes me time to settle in, adjust, get match practice in. As each match goes on I feel more and more comfortable. Today was, I am not going to say some of the best tennis I have played, because the rallies were really short but I feel like I have definitely got better."
After Australia's win, Kyrgios couldn't resist a sneaky dig at Murray and Watson on Twitter.
