Motor racing legend Peter Brock will be farewelled on Tuesday at a state funeral in Melbourne.

The 61-year-old was killed when the Daytona Coupe replica he was driving slammed into a tree during the Targa West tarmac rally near Perth on September 8.

Brock was honoured on Sunday with a commemorative plaque unveiled at the Australian Motorcycle Grand Prix at Victoria's Phillip Island.

Hundreds of people also made a pilgrimage to the crash site in Gidgegannup, near Perth, to lay flowers in his memory.

The day was an emotional one for Brock's former partner of 28 years, Bev, who provided a family photo of Brock for the Phillip Island plaque.

"To see a very personal photo of the man that we knew and loved makes it all the more poignant," she told Network Ten.

"He would be sitting up there thinking, `Yep this is good'. It is touching."

Tuesday's state funeral will be held at St Paul's Anglican Cathedral in central Melbourne from 11am (AEST) before a private service for the family.

A public memorial service also will be held for Brock at Sandown Raceway at Springvale, in Melbourne's south-east, on Friday, September 22.

Brock won nine Sandown 500 endurance races at the track between 1973 and 1984.
