The attacking midfielders tournament was sent into disarray when he was given a debatable straight red card in the Socceroos' opening Group D clash with Germany but he has praised the kindness of Evertonians who have backed him since the incident.
"I want to thank the Everton fans for their support during the World Cup," Cahill exclusively told evertonfc.com. "They know how much I love the Club so it means a lot when they back me when I go away with Australia.
"It was a really low point for me after the Germany game but to know the fans back at Everton were behind me meant a lot."
Cahill admitted it was tough to deal with, being sent off in such a major tournament, but said he is now ready to do the business and help get his nation into the Round of 16 with a win over Serbia in Nelspruit tomorrow morning AEST.
"I have become a stronger and better person for that sending-off against Germany. I disagreed with it but you have to get your head together and push on," he added.
"I am not a good watcher. I hardly got any sleep the night before the Ghana game thinking what if, what might have been.
"We can do the business. We take any criticism on the chin. We have had two difficult scenarios and two red cards. The way we can put it right is on the pitch. The chances we created with 10 men show how good we are.
"We have to get on with it. We have another crack against Serbia."
