At a State of Origin event on Wednesday, Opposition leader Bill Shorten confused Queensland Maroons with the Melbourne Storm as he backed the latter to win at the ANZ stadium.

Initially, Shorten said he would be backing the Maroons because his wife Chloe is from Queensland. However, the Labor leader, who was campaigning in Brisbane on Wednesday, corrected himself and said he would support Melbourne at the Origin event. “I also have to say the Storm are the underdogs slightly under the bookies market and I am partial to backing the underdogs,” the Mail Online quoted him as saying.

The Federal Member for Maribyrnong in Victoria also said that on the Marrons side, Melbourne Storm players like Cameron Smith are very well respected.

Shorten later posted a tweet apologizing to Maroons and Storms captain Smith. “Sorry … got your teams mixed up. Will be backing you and the Maroons tonight and the Storm this weekend,” he wrote on Twitter.

The State of Origin blockbuster event was also attended by the likes of Prime Minister Malcolm Turnbull and Treasurer Scott Morrison. The group had “let their hair down,” clicking selfies at the event. Morrison even got into the prank mood by sneaking into a photograph of Shorten with a Queensland supporter.

The prime minister also faced some friendly trolling earlier in the day by Steve Baxter, the River City Labs founder and the “Shark Tank” judge.

Turnbull visited the start-up hub in Brisbane on Wednesday for endorsing the $15 million to help investors, which is one of his signature innovation policies. However, Baxter, who is a Queenslander, presented a Maroons jersey to the prime minister, who is a Blues supporter. The gift was well received by the prime minister.

“A Maroon ambush! I was offered a Maroons jersey in Brisbane today – just as well it wasn’t the right fit! Go the Blues!” Turnbull wrote on Instagram after the event as quoted by the Business Insider.
