With a parade through Melbourne and fireworks painting the night sky, Victoria will light up in a kaleidoscope of colour to mark Australia Day.
More than 10,000 Victorians will line the streets of the state capital on Sunday to enjoy Melbourne's biggest people's march after the traditional flag-raising ceremony.
Many of the state's ethnic and multicultural communities will be on display, while Star Wars and Dr Who enthusiasts will also strut their stuff when the parade gets underway from Melbourne Town Hall at 11am (AEDT).
Away from the city, and in parks and backyards across the state there'll also be thousands of impromptu barbecues to mark the anniversary of the First Fleet landing at Sydney Cove.
But those Victorians not content with flipping snags, cracking tinnies and settling in for the Triple J Hottest 100 will have their choice of activities to celebrate the day.
