England flanker Chris Robshaw has urged the side to follow up last Saturday's win in Brisbane with a better performance in Melbourne as they go in search of a historic first series victory in Australia.
If selected the 30-year-old will receive his 50th cap for England on Saturday in a match which could see England clinch the series against the Wallabies.
And Robshaw said last weekend's victory in Brisbane will mean nothing if they do not follow it up.
“If we don’t win the series then it is all for nothing, it’s great to win one but we need to win two or three,” Robshaw told the RFU's official website.
“The series is everything, Eddie put it on the line as soon as we got here that we wanted to win the series and that is the mind-set.”
England beat the Wallabies by a record score last weekend and it retained their unbeaten record since the Rugby World Cup in September.
“For me it is the first ever game I’ve won in the southern hemisphere, so for me that’s pretty special in its own right and so it’s about kicking on,” added Robshaw.
“We still feel we have more to give, we had some defensive lapses and we let ourselves down with that.”
Head Coach Eddie Jones has already said that he expects a stronger Wallaby team on Saturday and Robshaw believes the first 10 minutes will be crucial.
“Generally they grow in the second Test and they’ve had an extra week together as well," said Robshaw.
"We can’t afford to go 10-0 down after 10 minutes. We need to start well in the first minute because we might not be able to claw it back this time.
“We know we’re in a good position but it’s about how we back that up. Every single day and every single training session we want to improve and make each other better so we can do that.”
