"We've known each other for a very long time, so that makes getting down together at the same end of the court pretty easy", Peers said. Australia has a slight edge given their team, but playing at home on their choice of surface (clay) will be huge for Belgium.
Kyrgios, who has been carrying a hip injury, goes into the match claiming: "I am not the professional tennis needs me to be". Goffin, ranked 12th in the world, has also been under an injury cloud since Roland Garros.
John Millman will take some juice out of the underprepared David Goffin's legs on day one, and Nick Kyrgios will reap the rewards on Day 3 when he plays Goffin sealing the tie for Australia, three rubbers to one.
Noah's team are favoured to progress to the final against a Serbian side sorely missing injured former world No.1 and 12-time Grand Slam victor Novak Djokovic, Viktor Troicki and Janko Tipsarevic.
Doubles stars John Peers and Jordan Thompson are in action overnight (NZ time) when they take on Ruben Bemelmans and Arthur De Greef.
With Novak Djokovic out of the Davis Cup semifinals, even a French lineup struggling for form is heavily favored to reach the team event final for the 18th time. Tsonga, who became a father this year and will be playing his first Davis Cup match of the season this weekend, managed to win just one match since a third round exit in Wimbledon, while Pouille's quick progression has been slowed down this season.
Aussie coach Lleyton Hewitt explained the switch, telling the Davis Cup's official website: "John is match hardened, he's played a lot of five-set tennis, particularly in NY".
Steve Darcis has the power to turn this tie in favour of Belgium. At the Rio 2016 Olympics, winning his opening match 6-0 6-0, the first man to do so.
Having taken the first set, Kyrgios was broken at the start of the second and although he saved three set points in game nine, the Australian netted a forehand, allowing Darcis to level.
Neither of the Belgians play a great deal of doubles but with Peers' regular Davis Cup partner Sam Groth not in the team, the Aussies will field a new-look doubles team.
Australian tennis player Nick Kyrgios has played down his comparison with Bernard Tomic, saying that he is in a category, different from his fellow countryman.
The Australian, ranked 20th in the world, suffered another early Grand Slam exit at the US Open last month and has endured numerous peaks and troughs throughout a tempestuous career in top-level tennis.
