The CA Brumbies completed their four-match French tour with a 20-6 loss to Top14 club, RC Toulon, at Stade Mayol.
England's 2003 Rugby World Cup hero Jonny Wilkinson was the chief destroyer for the home side, kicking four penalty goals before he was replaced in the 59th minute.
Wilkinson's chore was made easier with the CA Brumbies gifting a number of opportunities on the back of a problematic set piece. In total the ACT lost seven tighthead scrums and gave away an additional five free kicks on their own feed.
Lealliifano, who covered flyhalf, centre and fullback during the match and was among the CA Brumbies best, added a penalty goal of his own in the 54th minute after a 40-metre bust by replacement fullback Pat McCabe.
RC Toulon landed another penalty goal in the 66th minute before pushing over for a try from a close-range lineout to close out the match with five minutes remaining.
McCabe confirmed his appointment as 'Player of the Tour' with another standout display and made the most of his limited chances in attack, predominantly through his ability to make ground on the back of his kick return.
Hooker Anthony Hegarty was the only injury concern out of the match with a suspected syndesmosis injury to his ankle.
The CA Brumbies finish the tour with one win over Top14 Champions, USA Perpignan (17-0) alongside losses to CS Bourgoin-Jallieu (20-12), Aviron Bayonnais (37-21) and today's result against RC Toulon.
Despite this morning's loss, CA Brumbies Head Coach Andy Friend said the tour was a valuable learning experience for the playing squad and coaching staff.
"It proved to be a great chance for the squad to bond, particularly with the younger members, and the integration of these young players and the way in which they took their opportunities was a real positive.
"It was also a great chance to experience a different style of rugby and a different culture and it's given us a fantastic read on what we need to do to improve individuals as well as the team."
The side will return to Australia on Sunday.
