The RBS 6 Nations champions face the Wallabies in the final Dove Men Series clash at the Millennium Stadium on Saturday.
Wales have lost the last eight encounters against the Wallabies, the last three by an agonising combined deficit of five points.
But Hibbard reckons such heartbreaks and the success of the British & Irish Lions Down Under can pave the way to victory.
“We’ve been so close over so many games but now is the time to do it,” said Hibbard.
“We have been saying it so long and now we have to deliver. We targeted four wins from four, we can’t do that but three isn’t too bad and is something we can achieve.
“It’s been so close for so many reasons. We’re a bit wiser now, the boys have ‘been through some good experiences and we’ve been together a long time.
“Any person who beats the Wallabies, with no matter what side, is going to bring that experience to the party.
“In the third Test with the Lions we were physical and battered them for 60 minutes – that was the end of it, they couldn’t survive after that.
“It was intense but it was one of those situations where you don’t want to walk off the pitch, you’re willing to crawl of. You would do anything for the win because it’s that important.
“We have to bring that ferocity again. We definitely want to win this, we’re going to win this and we have to bring the intensity from the off and the physicality right across the park.”
But while Hibbard reckons Wales can take confidence from the Lions’ heroics in Australia, he insists the Wallabies are a much-improved team under Ewen McKenzie.
And he reckons New Zealand’s last gasp victory over Ireland on Sunday serves as a perfect reminder of the necessity to play for the full 80 minutes.
“Since the Lions they are almost a different team,” added Hibbard.
“They played well in the Championship and seem a different team over here, their confidence is high. It will be a tough one, probably the toughest of the last four years.
“Their pack has come under a lot of fire over the years but it’s one of their weapons now. You can’t say they are a weak pack, they never were, it was a myth. They’re a strong unit and it will be a big challenge.
“But we expect to beat these teams now and having gone down and won with the Lions and been so close with Wales over the years, that hurdle is not there any more.
“The Ireland game is a stark reminder of last year where Australia did it to us and scored in the last minute to win. We have to play the full 80 and can’t give them an inch because they’re very good at staying with you and then stealing it.”
