Reports say NSW Premier Kristina Keneally will soon announce that the annual Breakfast on the Bridge event will feature a football theme to support Australia's bid for FIFA World Cup 2022.

"I urge everyone in NSW to register for the public ballot and make the most of this chance to spend a Sunday morning eating breakfast on a grass covered Sydney Harbour Bridge," Keneally said in a statement on Sunday.

The Breakfast on the Bridge website features the slogan, “Come play at the world’s greatest picnic”. Come Play is also the slogan for Australia’s World Cup bid.

The special event is partnered by NSW Events – the same organisation behind the ongoing Sydney Festival of Football.

What’s more, the Socceroos play in Sydney 24 hours earlier against FIFA World Cup quarter-finalists Paraguay, further suggesting that football will be front and centre of this iconic event.

"Last year, the inaugural Breakfast on the Bridge captured national and international headlines, with images of the event seen by more than 100 million people across key tourism markets including Japan and the United States," said NSW Major Events Minister Kevin Greene.

The event sees the famous bridge shut to traffic with grass laid down on the tarmac as members of the public enjoy a breakfast picnic on an Aussie icon.

Around 6000 people are set to take to the bridge in what should be a major publicity boost for the bid.

The public ballot for a place at Breakfast on the Bridge opens on August 15 and the event happens on October 10.
