Tickets to Pink at the WIN Entertainment Centre are expected to be sold-out within hours after going on sale at 9am today.Almost 150 people queued outside the centre's Ticketek office in a bid to buy tickets to the Grammy-award winning singer's two gigs on Saturday August 22 and Sunday August 23. One clever mum, Rachel Bond from Dapto, arrived in the queue at 5am, armed with a laptop fitted with an air card.VIDEO: Pink fans queue outside the WIN Entertainment CentreMrs Bond, who was placed 35th in the queue, proved that online was quicker than in-line when the tickets went on sale.By 9.05am she had purchased ten, row-G tickets for the Sunday night show via the Ticketek website, beating the people who were third in line. "I have got three children, so we will all be going. It is my daughter (Demi-Rose's) 11th birthday when the concert is on, so it will be her birthday present,'' Mrs Bond said. "I tried the pre-sale tickets and I couldn't get any where I was happy with the seating, so I thought I would try today to see if I could get any better.''The excitement in the queues was heightened by a radio station competition, which promised to reimburse the first five ticket holders who arrived at the station with tickets and recited the Pink line, "I'm not here for your entertainment".After purchasing tickets, many people sprinted to the cars in a bid to reach the station first.One lucky daughter even managed to have her taxi-driver father ready and waiting in his cab to rush her to the station.For more coverage see Saturday's Mercury.
