The tourists were humbled inside three days in the Boxing Day Test and many are predicting a similar outcome at the SCG with an uncharacteristic green wicket and Australia's in-form four-pronged pace attack.
"We've spent a few days to try and get over that match, what happened and how we can avoid something like that again," Jayawardene said. "Teams do go through that sort of thing. It happened to us in South Africa last year at Centurion where we lost in two-and-a-half days and we bounced back in Durban to win the Test match."
He went on: "It's about guys owning responsibility about what happened and doing something about it.
"It is a strong Australian side but if we play to our potential and back ourselves then we can stand up to that."
An honest Jayawardene conceded the Sri Lankans had let themselves down during the tour, laying much of the blame at the hands of the batsmen.
"That's where our experience lies and that's where we control a lot of Test matches," he said.
"We need to make sure we take that control back whether it's the technical side of it or the mental side that we need to address.
"We have spoken about it but there's only so much you can talk behind closed doors - we need to go out there and perform."
