Head coach Andy Robinson insists England can still retain the World Cup next year despite suffering their worst run of Test defeats for 22 years.
Captain Pat Sanderson and Robinson reflect on another defeat
"I'm very confident that we can put out a team capable of winning the World Cup," he told BBC Five Live Sport.
"We'd have to work very hard to achieve that but with the right plans in place we can win it.
"Remember last autumn we destroyed Australia and narrowly lost to New Zealand, so we can get this right."
Saturday's 43-18 hammering by the Wallabies was England's fifth Test defeat in a row, and their 10th in 18 Tests under Robinson.
But he took solace from the performances of several players down under, even if he admits the backline needs urgent reconstruction work.
"Test rugby is a step up in class and the young players have done pretty well," he said.
Combined with the players back home, I think we have a side able to take on the world's best
"Peter Richards had a couple of starts and we're pleased with him. Mathew Tait did well, as did Tom Varndell.
"And again we have shown the depth we have up front - players like Ben Kay, Chris Jones and George Chuter did very well.
"We're developing outstanding international forwards and we just have to look at developing world class players in our backs."
England won 63% of the possession in Saturday's Test in Melbourne, but made little headway against the Australian defence.
"Our execution is a key area for us to really look at - passing, running angles, hard lines, being able to offload and support - because if you look at the possession, we dominated again," Robinson added.
"We have very good forwards, but we are looking to develop some quality in our backline.
"There are players here (in Australia), who put with the players back home, I think there is a side that will be able to take on the world's best."
