Anthony Albanese will be looking to kick a goal for the 'yes' vote in the voice referendum when he lines up for the official AFL Grand Final breakfast in Melbourne.

More than 100,000 people will fill the MCG on Saturday as Collingwood takes on Brisbane.

Before the game, fans, dignitaries and footy officials will gather at the Melbourne Convention and Exhibition Centre for the annual North Melbourne Grand Final Breakfast as the lead up to the biggest footy game of the year reaches fever pitch.

The prime minister's speech will likely focus on the 'yes' vote as the opening siren looms for polling day.

The vote on the Indigenous voice to parliament is only weeks away, with early voting to start on Monday before the October 14 poll.

The AFL was one of the many sporting codes to back the 'yes' vote this year, with Indigenous footy legends Eddie Betts and Michael Long among those putting their support behind the voice.

Long walked clos e to 800km from Melbourne to Canberra as part of his campaigning, recreating his famous Long Walk almost 20 years ago.

It's been two decades since Brisbane and Collingwood last faced off in a grand final.

The Magpies will be after redemption after the Lions took out their third premiership in a row - and their second consecutive flag against the Pies the last time they met in the decider.

The rivalry remains strong, with thousands of fans lining Melbourne streets for the grand final parade on Friday.

It was a return to tradition, with players travelling in a motorcade of utes rather than floating in boats along the Yarra River as they did last year.
