At the front of the queue were Unanderra sisters Shahna and Kara Fairley, who secured tickets for Shahna, 20, and long-time fan father David Fairley after camping for 14 hours.

"My father has been a very hard-core fan since his teenage years. He's got records, old T-shirts, banners," said Shahna, who was woken between 4am and 5am by a brief rain shower.

"He delivered our breakfast this morning and was ecstatic to find we were the number one people there.

"We got exactly what we were after. We definitely wanted to be standing and right in it. We're very happy."

Much of the conversation in the queue revolved around which songs from more than four decades of rock, would get an airing at the February 18 Sydney show.

The Fairleys will be hoping for Shahna's favourite - Dirty Deeds (Done Dirt Cheap) - and Jail Break, a staple of Mr Fairley's playlist for many years.

"He had blown his speakers from having it on full-ball," Shahna said.

AC/DC sold out concerts around the country within minutes when they went on sale yesterday, prompting promoters to claim it was the fastest-selling show ever to hit Australia.

Second and third concerts were being added to their February tour after long queues snapped up the first concerts on offer.

The Perth show sold out in just seven minutes, while tickets to two Sydney shows were also snapped up prompting promoters to schedule a third concert.

A second show was added in Brisbane and it is likely more shows will be scheduled across Australia due to the demand.
