What is being billed as Australia's biggest-ever boxing match will see young Australian Jeff Horn step into the ring with one of the all-time great fighters, Manny Pacquiao from the Philippines on Sunday.
Dubbed the "Battle of Brisbane", about 50,000 people are expected to flood into Suncorp Stadium, the home of the Queensland State of Origin team and the NRL's Brisbane Broncos.
In addition to the big crowd at Suncorp, there are expectations of a massive television audience. A large number of pubs and clubs will show the fight, as well as those who will pay to watch it at home.
The timing of the fight for early Sunday afternoon should also boost the audience in many crucial overseas boxing markets, including ESPN's millions of subscribers in the United States.
The fight for the WBO Welterweight world title is the classic pro versus local underdog. WBO refers to the World Boxing Organisation, one of the major associations within the sport of boxing.
Pacquiao, 38, has won more than 50 bouts in his long professional career, many of them against the best fighters in the world.
Horn, 29, is undefeated in his career but he has not fought anyone near Pacquiao's experience or talent. However, the Australian will have youth on his side, is a determined boxer and will have the support of the crowd.
Chairman of Tourism and Events Queensland Bob East said the fight could generate about $20 million in economic activity. Queensland has targeted events as a key plank in its strategy to boost tourism.
People often attend a sporting or cultural event and then add some leisure time around that, he said. Due to the international exposure from the fight, Mr East said there would be a lot of people getting a glimpse of the Sunshine State on Sunday.
"This fight has really resonated with people, there has been so much interest," he said.
The big bout is being promoted by Top Rank - which has the legendary US promoter Bob Arum - and Duco Events. Duco's Dean Lonergan said the company had been involved with big events before, such as the annual NRL Nines held in Auckland, but this fight was the largest the company had handled.
"For a big fight like this, you have to get four elements working successfully. First you have to get the sponsorship in place, then the sale of the corporate suites, then general admission tickets and then pay TV.
"All four have to go well for it to be a success. It has been hard work, but this will be the biggest event in Australian boxing, " said Mr Lonergan.
The fight locally will be shown on pay-per-view channel Main Event. Angus Pitt, general manager Foxtel on Demand, says interest in the fight has been very healthy. Typically most viewers sign on in the last 48 hours before an event.
"Early buys for Pacquiao v Horn have been very strong and we expect this to be one of our highest selling events of all time," said Mr Pitt.
