Dylan Alcott's awesome moment with Federer

Aussie wheelchair champion Dylan Alcott shared a brilliant moment with Roger Federer after his Australian Open triumph.

Alcott became the first man or woman in any division to win four consecutive titles at Australia's grand slam by beating top-seeded American David Wagner 7-6 (7-1) 6-1 on Saturday afternoon.

Channel 7 cameras caught the moment Federer congratulated Alcott in the tunnels of Rod Laver Arena after the Aussie's match.

Federer held back while Alcott received congratulations from a number of others, before surprising him with a classy handshake and a nice chat.

After one of the biggest fortnights of his life, Alcott said the dominant feeling was relief.

"Because of the ANZ ad, Will Smith build-up and Rod Laver last night, if I choked, I would have felt really flat," he said.

"But this is the icing on the perfect two weeks."

Alcott has been in millions on Australian homes as the face of bank ANZ's marketing campaign through the Open.

He also got his chance to show his on-court ability on Friday night when organisers threw his match with rival and great mate Heath Davison onto centre court and prime-time after Hyeon Chung's retirement against Federer in the men's singles.

That - and playing tennis with actor Will Smith - made it a memorable Melbourne Park campaign.

"It was a perfect storm," Alcott said.

"They could have put mixed doubles on but it's great t know I have the trust of not only Tennis Australia but (Channel) Seven saying 'no, we want Dylan. We want to put on Heath and Dylan.'

"Ten years ago I could have paid Channel Seven a million dollars to put it on and they would have said no.

"For the first three change of ends, 10,000 people stayed to watch.

"That's crazy stuff."

With hundreds of thousands more watching at home, it was a breakthrough moment for disability sport that Alcott cherished.

"I remember when I was a little kid I used to ask my parents and brother why I never saw anyone like me on TV," he said.

"Kids today won't have to ask that.

"That means the absolute world to me."
