In 2012, Hewitt won his single and doubles match against China in February, which allowed Australia to return to the playoffs where they lost to Germany. After defeating Chinese Taipei and Uzbekistan, Australia earned the right to get to the playoffs again in 2013. They ended up routing Poland 4–1 on their soil including a convincing 6–1 6–3 6–2 win for Hewitt over recent Wimbledon quarterfinalist Łukasz Kubot. In 2014, Australia crashed out 5–0 in the World Group first round on the French clay of La Roche sur Yon. Jo-Wilfried Tsonga beat Hewitt both in singles and doubles. Perths grass courts would then be hosting yet another playoff tie for Australia in September 2014. Hewitt won both his singles match (against Farrukh Dustov) and the subsequent doubles rubber (partnering Chris Guccione (tennis) v. Dustov and Istomin) in straight sets while up and coming Nick Kyrgios won his encounter with Denis Istomin to give Australia an unassailable 3–0 lead over Uzbekistan, thus enabling their country to return to the World Group in 2015. Sam Groth and Nick Kyrgios wrapped up a 5–0 victory a day later. Australia will open their 2015 campaign in Czech Republic for a 6–8 March tie that is one of two worst-case scenarios for Australia.
