Australia has already won a swag of Olympic gold with confirmation today that over 20 Aussie businesses have secured around $250 million in contracts for the London 2012 Olympics.

Colin Biggs, Austrade's London-based Senior Business Development Manager responsible for Olympic Games activity, said leading Australian infrastructure companies, and architects, as well as specialists in procurement, security training and sports management, have all secured contracts.

"Sydney is still viewed as the gold standard for Olympics so it's probably not surprising that Australian companies, who are recognised as world leaders in their often specialised fields, have been successful in securing contracts," said Mr Biggs.

"There are also many Australian nationals in key positions within the organising structure including the Olympic Delivery Authority (ODA) Chief Executive Officer, David Higgins."

Mr Biggs confirmed that there are still contracts available for the £10bn project in areas such as the development of the opening ceremony.

"We have noticed that the successful companies invariably pitch themselves as world leaders in their field, and stress their involvement either in previous Olympics or in similarly demanding events," he said.

"It's also worth noting that the organisers will often seek to appoint major, tier 1 contractors, and rely on the supply chain to manage the tier 2 and 3 levels of subcontracts. The target for many companies is therefore frequently not the organising committee.

"Beyond that, Austrade is in regular contact with key players to get more specific business intelligence on developing structure, priorities and timing of the organising committee and the many commercial organisations, and areas where Australian capability can make a contribution, including insights into how supply chains operate

"The London 2012 games will also provide an opportunity to form alliances with UK and European partners, allowing consortia to bid for future northern hemisphere projects, such as the Euro 2012 football tournament in Poland and the Ukraine in 2012, and the Sochi Winter Olympics in 2014 in Russia."
