Australian landmarks have been bathed in French colours as hundreds came out across the country to mourn the victims of a suspected terrorist attack.
At least 84 people are dead and even more injured in the French city of Nice after a man drove a truck into crowds celebrating Bastille Day.
Three Australians suffered minor injuries in the attack.
In Sydney, hundreds gathered at Circular Quay in an evening candlelight vigil to reflect on those injured and killed.
Earlier, the French flag was hoisted high above the Sydney Harbour Bridge as NSW Premier Mike Baird offered condolences to the people of France.
In Melbourne, the Victorian parliament and the Melbourne Star Observation wheel were bathed in blue red and white.
Numerous monuments in Adelaide, including the Town Hall and Adelaide Oval lit up in solidarity.
Perth City Council lit up their Council House with Lord Mayor Lisa Scaffidi saying "our hearts beat with their (victims) family and friends".
City Hall in Brisbane's CBD and Darwin's city council building also followed suit, lighting its facade with the tricolour.
Tasmania's Parliament House was flying the French flag at half mast.
One of the Australian victims, a young woman who was on a Topdeck coach tour, was released from hospital on Friday evening (AEST) and has rejoined her group.
"The doctors have given her the green light. She genuinely is OK," a Topdeck media spokesman told AAP.
Another Topdeck tourist, Australian student Tori Anderson was at the Bastille Day celebrations and saw the truck ploughing through the crowd.
"Dead bodies were just tangled everywhere and we just had to run for our lives," she told the Nine Network.
The driver, believed to be a 31-year-old man of Tunisian origin, was deliberately swerving along the road pointing a gun out of the truck window.
French police, who shot the driver, discovered the truck contained guns and grenades.
Governor-General Sir Peter Cosgrove, who is in France for centenary of WWI and Bastille Day events, briefed Malcolm Turnbull on Friday, with the Prime Minster describing the incident as a "murderous act of terror".
