Stephen Moore the merrier: Unity under Michael Cheika pivotal to Wallabies’ success, says skipper

Australia have found unity in a year under tough-talking coach Michael Cheika, team skipper Stephen Moore said ahead of Sunday's Rugby World Cup semi-final clash with Argentina.

The 32-year-old hooker -- who will win his 101st cap at Twickenham against the Pumas -- said the change in mindset among players has been the pivotal factor in Australia reaching the World Cup semi-finals.

Cheika's focus on character has transformed a demoralised faction-riven outfit, he said.

The coach has inflicted a tough training regime aimed at squeezing every bit of skill out of the team. He also demands loyalty to the cause.

"I think the biggest difference since he arrived is probably getting everybody on the same page and getting everyone aligned in the same way with regards to what we stand for, who we are playing for and who we are representing," Moore said.

"He has succeeded in bringing players closer together from different teams across Australia and creating special bonds.

"We have become a very tight-knit group.
