Robson and Murray will face Spain in the final
Andy Murray and Laura Robson earned a place in the Hopman Cup final after they sealed a 2-1 victory over Russia in the decisive mixed doubles.
The British pair beat Igor Andreev and Elena Dementieva 6-4 6-7 7-6 to finish top of Group B and set up a final against Spain.
Earlier, Murray thumped Andreev 6-0 6-1 after Robson was beaten 6-4 6-0 by world number five Dementieva.
"I have to say thanks to Laura because she played great," said Murray.
"In the mixed, the guy is supposed to try to dominate and help the girl but every time I tried that we lost the point, so I left it to her after that."
Murray and Robson will now have to beat Spain's Tommy Robredo and Maria Jose Sanchez Martinez to win the title after the Spaniards beat Australia's Lleyton Hewitt and Samantha Stosur.
The Spanish team will go into the final as favourites but Murray and Robson have formed a strong partnership and won all their mixed doubles matches in the competition.
And while former Wimbledon junior champion Robson, 15, has lost all three of her singles matches this week, she believes she can beat Martinez Sanchez, who is ranked 26th in the world.
"I played her in a practice set before the tournament started, and I won," she said. "I know it's only practice but I am telling myself practice is basically a match, so technically I am 1-0 up."
Murray, who has been unbeaten all week, has faith in his young team-mate.
If I play like that, then I can win the Australian Open for sure
"Laura's definitely got a chance in the singles and we'll have to wait and see what happens," Murray said. "I want to win the tournament now."
However, the 22-year-old knows he also faces a tough ask against Robredo, who has also won three consecutive singles matches and has triumphed twice in four encounters with Murray.
"It's important to stay patient and it's going to be a tough match because he's played great this week, but if I play well I've got a good chance of winning," Murray said.
Either way, the Scot believes his form is coming good at the perfect time with the Australian Open due to get under way in 10 days time.
"If I play like that, then I can win Australia for sure," said Murray after his win over Andreev.
"I didn't feel like I was making any bad decisions. I didn't feel like I was overplaying and it was just lucky shots that were coming off.
"But I need to make sure I do it in a couple of weeks and play like that from the start of the tournament to the end."
