Andy Robinson hailed Scotland's first win over Australia for 27 years as "the most courageous performance I have ever been involved in".
Speaking after one of the greatest rearguard victories in recent Test history, Robinson ranked the bravery of his side even above that shown by England in winning the 2003 World Cup.
"I've said to the team that is the most courageous performance I've ever been involved in," Robinson said after the 9-8 triumph, secured after Matt Giteau missed a stoppage-time conversion for the tourists.
"The effort that has been put in, the way the team got off the floor and defended - and credit to Graham Steadman for the way he's put this defence together - was incredible.
"The amount of ball that we gave Australia to play with throughout the game and the courage that the players had to get up and keep knocking them over.
"We needed a bit of luck, I thought the guys worked hard to establish that luck.
"If we can perform like that, with that same courage every time we go on the pitch, then we can grow a team and that's what we're about now. That's the baseline for our performance, the guys have got belief."
Australia completely dominated the match, missing four clear tryscoring opportunities before Ryan Cross finally went over.
Giteau also missed a point-blank penalty and close-range drop goal as Scotland enjoyed the rub of the green throughout.
"I'd like us to play with a little bit more ball and want to keep hold of it a little bit more," joked Robinson.
"But that's the levels that we've got to improve and it just shows you we do have to improve with our ball in hand. That's a platform now for us to be able to do that."
