Queenslanders have seen out another Australia Day with barbecues, cockroach races and growing calls to change the date of the national occasion.
Dozens of families and individuals from around the world became Australians in citizenship ceremonies across the state, with the country's largest taking place in the heart of Brisbane.
Brisbane Lord Mayor Graham Quirk said almost 600 people had become official Australians, further adding to the 28 per cent of Brisbane residents born overseas.
"We simply say to them, thank you for doing that," he said.
Hundreds gathered at state parliament to rally in support of growing calls to change the date of Australia Day 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.
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.
He called on state and federal governments to hear the voices of indigenous Australians and "just go ahead" to make the change.
Meanwhile, revellers donned Australian flags, Aussie-themed onesies and even stuffed toys to attend the cockroach races at the Story Bridge Hotel, which has been running since 1982.
Crowds flocked to South Bank for a night of fireworks, hours after 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, a Queensland Police spokesman said.
