As they have done for numerous years, the cities of Fremantle and Cockburn will join forces to put on a day of family-friendly activities.
Things will kick off in Coogee with the Big Aussie Day BBQ Brekkie starting from 8am.
It is predicted more than 3000 people will venture down to the popular beach to take part.
After lunch, Fremantle will take centre stage with a second round of activities before a fireworks display over the Indian Ocean about 8pm.
More than 50,000 people are expected to flood Fremantle to watch, with 30 per cent of those people from Cockburn.
More than 300,000 people were estimated to have ventured on to the banks of the Swan River to watch the City of Perth’s Australia Day Skyworks in 2015.
But rather than fight to tempt some of those south to the port city, Fremantle community development director Marisa Spaziani said the focus was on ensuring people have a good time.
“Freo takes pride in being a relaxed and comfortable alternative to the Perth City activities,” she said.
“Our focus is on offering plenty of high quality, family-friendly entertainment for Australia Day which is easily accessible by public transport.”
Cockburn spokeswoman Samantha Seymour-Eyles said there was no competition with the City of Fremantle.
“For the City of Cockburn, the answer is no,” Ms Seymour-Eyles said.
“Our Brekkie event is held in the morning before people head off to visit family and friends, or to see the fireworks.
“The City’s event is family-friendly and local.”
