The 28-year-old made his international debut against France in Paris back in 2000, eventually breaking Frenchman Oliver Magne's world record for the number of appearances by either a blindside or openside.
"You don't play the game to reach these milestones but it was nice news to receive after the game and to surpass a great player like Olivier Magne is a fantastic achievement," Smith told AAP.
Smith, who was voted Australia's Super 14 Player of the Year for the third successive year in 2008, now needs to make just 10 more appearances to reach 100 Test caps, something he believes he is capable of.
"I've got plenty of time and plenty of games ahead of me. It's a possibility that I can reach that mark.
"My body's feeling really good at the moment and I'm enjoying the football that I am playing so hopefully if the time comes I'd like to make that mark."
