Queenslanders have marked Australia Day with barbecues, cockroach races and growing calls to change the date of the national occasion.
Dozens of families and individuals from all over the globe have become new Australians at citizenship ceremonies across the state, with the largest in the country staged in Brisbane.
Lord Mayor Graham Quirk officiated at City Hall, welcoming about 600 people he said would add to the city's rich diversity, with 28 per cent of residents born overseas.
"You see incredible stories of hardship, in some cases people that have suffered torture in their previous countries, right through to people that have come here in a professional role," he said.
"We simply say to them, thank you for doing that."
At the state's parliament, hundreds gathered in support of growing calls to change the date from January 26 out of respect to Aboriginal and Torres Strait Islanders, who recognise the occasion as a day of mourning.
Wookku Fogarty, a traditional owner of the Yuggera people, said January 26, 1788, marked the beginning of his ancestors being slaughtered.
"That day marks the day of the first killing and the invasion of our country and to celebrate it would disrespect my ancestors ... and the loss of life," he said.
Marching through the city streets to South Brisbane's Musgrave Park, Mr Fogarty said a growing number of non-Indigenous Australians were beginning to recognise the significance behind calls to change the date.
"Before, they had the true history hidden from them, and a lot of them didn't realise they were disrespecting Aboriginal people," he said.
Mr Fogarty called on state and federal governments to hear the voices of Indigenous Australians and "just go ahead" to make the change.
"You don't need a vote because there is a general understanding among the population that it's the wrong date to celebrate."
Meanwhile, revellers donned Australian flags, themed-onesies and even stuffed toys to attend the cockroach races at the Story Bridge Hotel, which has been running since 1982.
But insects weren't the only hot favourite, with the Colmslie Hotel's charity toad race returning for another year.
At South Bank, where crowds are expected to gather for a night of fireworks, four men on a makeshift raft caught the attention of water police.
The group, intent on floating from West End to Kangaroo Point, were encouraged back to shore at the halfway point out of safety concerns, police said.
