Geelong premiership captain Tom Harley says he still needs more time to decide whether to retire from the AFL.

Harley is expected to soon announce an end to his career after captaining the Cats to a premiership for the second time on Saturday, following their drought-breaking win in 2007.

But the defender, who joined his teammates in a parade through the streets of Geelong on Tuesday, said constant celebrations since the grand final win had made it impossible to have the discussions he needed before making a decision.

"I've said it all along, it's really just exhale for a couple of weeks and talk to the right people," Harley said.

"I haven't really spent any time with the coach since the game, so I'm looking forward to just sitting down and talking about all of that and making a decision."

Harley said the potential to win a third flag with the Cats was an incentive to play on, but it was also important to leave at the right time.

"I guess you have to in life just pick your times with certain things and I'll back myself in to make the right decision when the time comes," Harley said.

The skipper was speaking in a mayoral robe, after being appointed Mayor of Geelong for the day, in front of a huge crowd of fans who had packed the city streets to celebrate the premiership.
