The Warrington utility player was a late call-up for his Test debut when prop Alex Walmsley pulled out on the day of the game with a virus.
He was then thrust into action early against the Kangaroos when Sam Burgess limped off with a knee problem that England said will see him return “earlier than anticipated”.
But despite having played just five times this year because of his own long-term knee injury, Currie more than held his own on his international debut in the 18-4 defeat.
And he says the team has taken heart from a gutsy effort that was not reflected in the scoreline after eight Aussie points in the dying stages.
Currie said: “One hundred percent I’m more confident we can beat them despite a defeat. We’ve been confident all along and we know we’ve a really good shot at winning it.
“Even though we lost we’ve come away with some confidence.
“I don’t think they won it, it was more a case of us losing it in a way – we made some silly errors we’re not used to making, especially in the first half.
“They took advantage – that’s all they do. They stick in the game, they don’t make errors, they just keep grinding away.
“That’s why the Aussies are the number one team at the moment – they just keep going and don’t get bored of what they’re doing.
“We just need to match them for that and I think we can and come out on top.
“They might have broken through us a few times but to show the character we did to turn up for each other, to still make those cover tackles, was great.
“There are still a few things we need to iron out in attack but we can beat these.”
Winger Jermaine McGillvary emerged from the game with significant credit after scoring England’s only try, causing the Kangaroos problems all night and making crucial interventions in defence.
Others to impress included replacement hooker James Roby, winger Ryan Hall and half-back Gareth Widdop, while Currie did his chances of a permanent spot no harm with a solid display despite his lack of action in 2017.
He added: “I found out I was playing in the morning.
“Obviously, all week Alex has been 50-50, he picked up a virus early on and unfortunately he couldn’t shake it off.
“I was prepared as though I was going to play and I ended up playing.
“It was fast and tough.
“I’ve not played too many games but I felt good and really fit – but we know we can beat them now.
“We’ve lost a game but if you ask anyone, they’re not too downhearted.
“We know we can play a lot better and the tournament isn’t won yet, is it?
“We’ve got to beat Lebanon and France, move on and hopefully meet the Aussies again in the final.”
