Dating back to the bronze medal play-off at the 2011 World Cup, Wales have lost seven times to the Aussies in 20 months leading some to suggest there may be a mental barrier for the 15 Welshman in Warren Gatland's squad to get over.
But North, who helped Wales retain their RBS 6 Nations crown earlier this season, is confident the blend of all four nations will create a team with more than enough quality to seal a series win.
The last time the Lions came together when they toured South Africa four years ago, North was still a pupil at Llandovery College.
But having been selected, the 21-year-old believes all the hard work put in since then with the Scarlets and Wales at international level has paid off.
"When you start playing rugby you want to play at the next highest level and work your way through the systems," North told Wales Online. "I progressed to the Scarlets and Wales. Then you move on to the next challenge, which is here now.
"It's been a lot of work to be here but it's paid off, not just for me but the others in the squad. It was the best feeling in the world when I heard my name in the squad. It was pretty awesome, surreal.
"It was unfortunate to lose the last four Tests against Australia [with Wales] by an average of something like four or five points. It was horrible.
"As Wales I think we learnt our lesson. Now going to Australia with the Lions we have got quality from other squads sprinkled in.
"It could be a whole different starting team from what people think and that could be the difference in pushing on and getting that Test win."
