Tim Cahill said that "this moment" was as much Martin Boyle's "as it was his." One last time, the Aussie talisman knew how to motivate his team best. 

The retiring legend presented Boyle with a signed shirt before the Lebanon match, inspiring him to saviour every moment he spends in the green and gold.

Boyle may never have stepped foot in Australia before this Socceroos camp but the 25-year-old Scotsman-cum-Aussie looked right at home on the wing, scoring a brace and registering an assist on his starting debut as Graham Arnold's side cruised to a convincing win over the 82nd ranked Lebanese.

"I hope I made my family and teammates proud," Boyle said.

Showing that he's assimilating into Australian culture, Boyle even had a crack at our national cuisine.

"I like the timtams but not the vegemite, I've had a few packets," he laughed.

After 108 caps, 50 goals, our first goal at a World Cup, our first at an Asian Cup and a never-to-be-forgotten impact on the world game down under, it was a Scotsman who gave Cahill the send off he deserved in front of a rapturous crowd in Sydney.

"I'm so proud," Cahill said after the match.

"Part of me feels so happy. I didn't want to cry because I'm so happy inside. I've always put my country first, I still can't believe I'm fully retired as a Socceroo. We can watch some videos.

"We've booked a beautiful holiday and now I'm just going to support Australian football. Being an Australian and enjoying the sport is the best thing for Tim Cahill now."

The reasonably inexperienced Socceroos lineup dominated through their newfound import who linked well with fellow newcomers Awer Mabil and Rhyan Grant, as a new-look Australian outfit began to find their feet.

It wasn't the fluid attacking football that Australians witnessed in spates against South Korea, but it didn't need to be. Lebanon, who are on a strong run of results under experienced gaffer Miodrag Radulovic, presented little threat, failing to register a shot on target. 

In the one ongoing concern for Arnold, once again Australia's out-and-out number nine was nearly invisible, with Jamie Maclaren's replacement, Tomi Juric, failing to make an imprint.

This was the last test for Arnold's team until their Asian Cup campaign kicks off - for the first time without their leading light in this confederation - on January 6 against Jordan. 

"Well I suppose this is the only time you're going to see me cry," Cahill said at a post-match ceremony.

"I want to say thank you to my family, the sacrifices they made for me is the only reason I'm fearless when I step onto that pitch.

"I want to thank the coaches, the players, without you I'd be nothing. Honestly, nothing. Now the most important people as well, are the fans. 

"I just want to tell you all, this is just as much for you as it is for me."
