'Schoolyard bully': Healy takes aim at Aussie fresh faces

Former Wallaby coach delivers stinging rebuke to Australia after defeat

Healy calls for 'ruthless' approach to next World Cup

Former Wallabies coach John "Knuckles" Healy has launched a blistering attack on Australia's underperforming squad following their humiliating defeat to Scotland.

The Wallabies slumped to a 15-13 loss in Edinburgh last weekend, their ninth defeat in their past 11 Tests.

Healy, who coached the Wallabies to the 1991 World Cup final, said the team had become a "laughing stock" under current coach Dave Rennie.

"We're getting beaten by Scotland for Christ's sake," Healy told The Australian newspaper.

"We're a laughing stock. We've got no direction, no leadership and no discipline. It's a disgrace."

Healy said Rennie had failed to get the best out of his players and called for a "ruthless" approach to the next World Cup.

"We need to be ruthless. We need to cut out the dead wood and bring in some new blood," he said.

"We need to start winning again. We need to be feared again. We need to be the Wallabies of old."

Healy's comments come amid growing pressure on Rennie, who is now in his third year as Wallabies coach.

The Wallabies have won just 10 of their 24 Tests under Rennie, and they are currently ranked ninth in the world.

Rennie has defended his record, saying he is building a team for the future.

"We're not where we want to be, but we're making progress," Rennie said.

"We've got a lot of young players in the team, and they're learning all the time.

"We're going to keep working hard, and we're going to turn things around."

The Wallabies will have a chance to redeem themselves when they face England in a three-Test series in July.

However, Healy believes the Wallabies will need to make significant changes if they are to have any chance of success.

"We need to be more physical. We need to be more aggressive. We need to be more ruthless," he said.

"We need to be the Wallabies of old."
