Australia head coach Michael Cheika apologised to the country's supporters are losing the Test series to England on Saturday.
Despite dominating possession in the second half the Wallabies couldn't find that second try required to take the lead in Melbourne, with Owen Farrell's late score settling the series.
The third Test awaits next week in Sydney with Australia now desperate to avoid a whitewash.
Cheika felt his side did enough to create chances to add points on the board, but let themselves down with their execution.
"Obviously, we're very disappointed and we apologise to our fans," Cheika told reporters.
"Honestly, we've had such great support and it's very disappointing to me – too many errors; too many dropped balls at key moments.
"(We) had plenty of opportunities to score, dropped the ball on several occasions close to the line and I don't think we trusted our skills in the key moments."
Wallabies captain Stephen Moore backed up Cheika's comments but also credited England for their efforts over the last two Test matches.
"We've got to own this. I feel for the fans," Moore said.
"England deserved to win both Tests and we've got to be better."
