Justin Langer insists his players haven't suffered any mental scarring from the summer despite admitting he himself lost sleep over fears of a loss to Sri Lanka at the Gabba.
Fresh from dropping a home series to a team from Asia for the first time earlier this summer against India, Langer had a number of other records to defend in Brisbane.
Australia hadn't lost a Test at the venue for two decades, while Sri Lanka has also never won a Test match in the country in 14 attempts following the hosts' innings-and-140-run victory on the weekend..
"I kept thinking before the game, imagine if we get beaten by Sri Lanka at the Gabba," Langer said.
"That's why I haven't slept much the past week. Hopefully sleep a bit easier (now)."
But he insists the losses haven't done damage to a group who have already endured one of the hardest 12 months in Australia's rich cricketing history.
The Aussies are on track to reclaim the Warne-Muralitharan trophy with either a win or draw in Canberra, but the Border-Gavaskar defeat to India was one of four series losses across all formats this summer as well as a one-off Twenty20 beating by South Africa..
"We were 1-1 after Perth. It was a real arm-wrestle wasn't it? It's not mental scarring," Langer said of the Indian Tests..
"They're young guys playing a really tough series. I think it's an unbelievable learning experience.
"We talk about the bigger picture of this team. Regardless of how you look at it, it's a very young Australian cricket team from what we've been used to.
"There's no scarring there. Just adds a few layers to their character."
Canberra's Test is Australia's last of the summer, and marks a crucial chance to end the home season on a high note ahead of both a World Cup and Ashes year for the hosts.
"Confidence. It's not even a cliche. You've got to build confidence," Langer said.
"Winning is really important."
