Hundreds of Ellen fans have flocked to the Sydney Opera House for the chance to fly to Los Angeles and appear on her popular US talk show.
Arena TV have announced via Twitter that fans will be able to compete in a "dance off" to win tickets.
Get down to the Sydney Opera House! Ellen is filming a LIVE dance off this morning & 2 lucky fans will win a trip to see her show in the US!— ArenaTV (@ArenaTV) January 21, 2013
Organisers said about 250 people had made their way to Circular Quay by 8am (AEDT) on Tuesday, clutching packed bags and their passports in response to a bombshell announcement by the show's executive producer Andy Lassner.
Lassner announced on Twitter on Monday that at least one lucky Australian would fly to the US with the show's team, which is currently Down Under scouting locations for when the show and its studio audience come in March.
Ellen also promoted the event to her more than 16 million followers.
Grab your passport & get to Sydney Opera House! You're gonna be on my show. Also, bring an overnight bag. I'll explain when you get there.— Ellen DeGeneres (@TheEllenShow) January 21, 2013
The winner (or winners) will be plucked from the crowd during a live cross with Ellen DeGeneres at her Californian studios at 11am, organisers said.
They will then be whisked to the airport for a 3pm flight to LA.
Before I go down under, someone in Sydney's gonna have a chance to come up over. I hope you're free tomorrow at 9:30am.— Ellen DeGeneres (@TheEllenShow) January 21, 2013
Christian Burke, 21, arrived at the Opera House at 5pm on Monday.
He said he resigned from his job two weeks ago in preparation for Ellen's visit to Australia and to concentrate fulltime on his Facebook page, An Aussie Backyard Barbie for Ellen.
"I love Ellen. I just wanted to be here and have the chance to meet Ellen, and thank her," he told AAP on Tuesday.
"I think my chances of going to LA are slim to none, but I just wanted to be a part of it.
"I also forgot my underwear."

Many other fans arrived at the Opera House in costumes or draped in the Australian flag.
Lizzie, Kay, Justine, Ash and Mere, from Peakhurst, painted themselves blue - in honour of the show's blue theme.
"We've been here since 6.30am," Justine said.
"The atmosphere has been great, it just shows how dedicated Ellen fans are."
Other fans held up handmade signs, while one sleeping baby had a T-shirt that read "pick my mummy Ellen please".
