In what Hewitt predicted would be a five-set clash, the tie will go on the line when Kyrgios takes on world No.5 Alex Zverev in Sunday's opening reverse singles rubber.
Australian team captain Lleyton Hewitt hinted he might have played in Saturday's doubles but resisted the temptation, pairing Ebden with world number four doubles specialist Peers.
The storm surrounding Bernard Tomic's sledge a week ago that the team could not win a Davis Cup without him nonplussed some players and annoyed Hewitt, but the truth is Australia have not had the depth of players to win a Davis Cup since 2003.
Kyrgios won the Brisbane International to start the season but he said he would probably hand that back if it meant getting Australia through to the Davis Cup quarter-finals. It sucks. I had one eye on this Davis Cup tie throughout the whole Aussie summer.
De Minaur pushed Zverev for nearly four hours in Friday's first singles match but Australian captain Lleyton Hewitt said he had no intention of replacing him with Brisbane's John Millman, who always plays well on his home court.
"He has played so well for me in the past - hopefully he can go out there and do it again".
"He's in their team for a reason - they're a world class team and we know to expect the best from them", Ebden said. I would have given up my Brisbane title to have won this tie.
The highly-strung player appeared to be struggling with an elbow injury that slowed his serve and left him vulnerable to Zverev's counterattack.

"I thought Nick was playing for sure". Does he play qualifying in the (United) States or back himself to win a couple of matches in qualifying at ATP level, " Masur said.
But it was 30-year-old journeyman Puetz - in just his second Cup tie - who stood tall, thrashing forehand victor after forehand victor as Germany prevailed in a rubber lasting nearly four hours.
"My serve is my biggest strength".
Hewitt has poured his heart and soul into the Davis Cup but has some thinking to do after the weekend.
Zverev - who was pushed for nearly four hours before seeing off 18-year-old Alex de Minaur in five sets on Friday - was rarely troubled.
The visitors sprung a late change, replacing Peter Gojowczyk with Jan-Lennard Struff but it was doubles partner Tim Puetz who proved the difference in the 6-4 6-7 (1-7) 6-2 6-7 (4-7) 6-4 win at Pat Rafter Arena.
