THOUSANDS of proud supporters flocked to the Brisbane CBD on Friday to welcome home Queensland's Olympians.

Foot and vehicle traffic in the city slowed to a crawl at midday as people packed into Queen Street mall to watch the Olympic team's ticker parade.

The athletes, including gold medal hurdler Sally Pearson and silver medal diver Brittany Broben, shook hands with fans donning green and gold colours before making their way to a stage at Brisbane Square.

Premier Campbell Newman put the success of the Sunshine State athletes into perspective and pointed out their medals accounted for 41% of all medals won by Australian athletes at the London Olympic Games.

"It comes as no surprise to Queensland that, once again, this state excelled," he said. "Everybody in this state is proud of the men and women in front of us today. It does not matter if you came back with a medal or not; we are proud of you..."

There were 33 Queensland athletes who brought home medals for Australia, including four of Australia's seven gold.

The Ladd family from the Sunshine Coast sported olympic memorabilia, including a facemask and Aussie zinc, as they waited eagerly for the sport stars to make their way through the crowd.

Nine-year-old Harry, who had been studying the olympics in class, and six-year-old Lexie were able to take the day off school for the event.

"We wanted to show the kids what things are like as they see things on the news but don't understand the gravity of it," mother Rachel Ladd explained. "Here they can understand the significance of it."
