With manager David Moyes and captain Phil Neville bidding their farewells, the Australian international also made one last appearance on the Goodison Park pitch after returning for the first time since joining New York Red Bulls.
"It's something that I will never forget. I'm really happy that I did it and I was welcomed back by the gaffer and the chairman. It was something special," Cahill told evertontv.
"I haven't been back here to say goodbye to the fans. This was the first time I have been back to Goodison, just to pay respects to the fans and the gaffer. It's the end of an adventure for all of us.
"I can't say a big enough thank you to the fans and how much they mean to me. Every time I play football I think of the fans and even though I have moved on they have been one of the biggest influences on my career.
"I would just like to say a massive thank you to them."
