Warburton grew up wanting to wear the famous red jersey yet he knows injuries and form could yet prevent him from fulfilling that goal Down Under.
"It's been at the back of my mind since I was a young boy really. I've always wanted to play for the Lions," Warburton told Sportsvibe TV.
"My dad bought me a Lions shirt with the No7 on the back when I was about 14. It's something I've always wanted to do but - although I'm not superstitious - I wouldn't want to jinx myself.
"With me, it's always injuries permitting, really. I did well for the first six months of last season and then my body started creaking.
"I missed a couple of Six Nations games and a lot of regional games and if that happens to me again this year, I won't be in contention.
"Trying to stay fit is going to be the number one priority for me this year. The medical staff at the Blues and Wales have done a great job so far. With their support, hopefully, that can open the door for me."
Warburton is well aware of the sense of pride attached to anyone who wears Lions colours, something he feels is particularly prevalent in Wales.
The 23-year-old would love to join an illustrious list of Welsh Lions that includes the likes of Gareth Edwards, Barry John, Mervyn Davies and JPR Williams but he knows performing for club and country has to come first.
"Players who have had Lions status in Wales, I wouldn't say it makes them immortal but they're very highly thought of," added Warburton.
"I always give Leigh Halfpenny a lot of stick because he played for the Lions, but it's only because I'm envious.
"It's something that every player in Wales would love to do. It's obviously been a massive motivation of mine since the days when I was younger.
"If I was lucky enough to play for the Lions, I'd be absolutely over the moon but the first thing for me at the moment is making sure I get some club rugby under my belt.
"There's a lot of competition in the national squad now with the emergence of guys like Justin Tipuric and Josh Navedi at the Blues so I've got my hands full there."
