St Kilda and Geelong say expected wet conditions for Saturday's AFL grand final won't lead to any last-minute team changes.

Melbourne turned on a wet, windy and miserable day for Friday's grand final parade through the city centre, and more of the same weather is expected for Saturday's premiership decider.

But Geelong coach Mark Thompson said the prospect of a wet MCG would not force any late changes to the Cats team.

"We won't change anyone unless they get a virus or crook back. The conditions won't change our lineup at all," Thompson said.

Lyon said he was confident the 22 the Saints had selected would be able to cope with the weather - wet or dry.

"We'd like to think we've put a game plan together that can handle any dimension, any conditions," Lyon said.

"From our perspective it (the weather) is not a controllable. It's the elements, it's what makes the game's great.

"You've got to able to stand up in all conditions and we're looking forward to the challenge."

Despite the wet weather on Friday, Melbourne's city centre was packed with fans of both clubs.

Geelong are aiming for their second premiership in three seasons, while the Saints have won just one flag - in 1966.
