Her devastated son was left in tears as they left the stadium.

“I spoke to a dad and his son on the way back to the train who had the same issue. I saw at least five groups get told their tickets were cancelled, and the line had at least 100 people waiting who were sent from the gates to the box office,” she said.

Later on Wednesday night, she posted a screenshot to Facebook appearing to show that tickets she had bought to a Billie Eilish concert had also been sold.

Comment has been sought from Ticketek.

Healey said later on Thursday the company’s managing director had reached out to her, promising to return her tickets to Billie Eilish, offering tickets on the sideline for the upcoming Broncos clash with the Bulldogs, and refunding the Origin tickets.

Carter went on KIIS radio this morning, where he met and chatted with Broncos star Corey Oates. His mother said she had also made a cyber fraud complaint.

“Hopefully the bank account can track down where the hackers are coming from and shut them down,” Healey said. “Never mess with a mumma bear with an upset baby.”

Asked on Thursday about reports of similar incidents, Queensland Deputy Police Commissioner Cheryl Scanlon said they were concerning.

“That’s a distressing thing for anybody, particularly when you’ve paid out significant amounts of money, so those things need to be addressed and reported,” she said.

“It’s very disappointing to hear that, it’s very disappointing for the organisers of those events, but also if you’re a mum and dad and you’ve paid out good money for something ... if that’s the case, we’d expect there would be reports today to us about that.”

Scanlon said it was best to buy tickets off legitimate and reputable suppliers of tickets.

Ticketek Marketplace is a secondary site operated by Ticketek that enables people to legally resell and buy tickets for up to 10 per cent more than their original face value.

Once tickets are resold, the original barcode is cancelled.

Ticketek was the target of a major data hack last month, which exposed the private details of thousands of customers.

At the time, Ticketek said information belonging to Australian customers, including names, birth dates and email addresses, had been taken from a cloud-based platform “hosted by a reputable, global third-party supplier”.
