Melbourne's John Peers and Finnish teammate Henri Kontinen stand in the way of an historic 17th grand slam doubles title for American pair Bob and Mike Bryan.
No.4 seeds Peers and Kontinen ended the impressive Australian Open run of local wildcards Marc Polmans and Andrew Whittington on Thursday with a 6-4 6-4 semi-final win.
The third-seeded Bryan brothers booked their final berth when they accounted for Spanish pair Pablo Carreno Busta and Guillermo Garcia-Lopez 7-6 (7-1) 6-3.
"Kontinen and Peers are one of the hottest teams on the tour," Bob Bryan said.
"They had a good month at the end of last year so they have an incredible run going.

"We have a lot of stuff to work on in the next couple of days."
The Bryans are the most successful doubles pairing of the Open era with 'The Woodies' - Australian pair Mark Woodforde and Todd Woodbridge - next best with 11.
However, Woodbridge also has 16 grand slam titles having won five more after teaming up with Swede Jonas Bjorkman after Woodforde's retirement.
This year's Australian Open has been a welcome return to form for the Bryans, who won their 16th grand slam title at the 2014 US Open.
At 38, the twins, who recently retired from Davis Cup competition, are in the twilight of their careers but their belief in their ability remains strong.
"I feel like we have that twinkle back in our eyes" Mike Bryan said.
"But if our career was a book this would be the final chapter or two ... we see the finish line,.
"We both can see that this is one of the last times that we'll be in Australia, so that's making us a little extra eager to go out there and play some good tennis."
