THERE'S still two weeks until One Direction hit Brisbane, but over-excited Ipswich fans Veronica Horvath and Hannah Graham can hardly get to sleep at night.

The girls bought tickets to the boy band's Queensland show 18 months ago and can hardly believe they will get to see their teen idols.

The band is currently in Melbourne and the members' arrival in Brisbane is expected to create mayhem not seen since the Beatles hit the city in 1964.

The Bundamba teenagers missed out on tickets to last year's shows, when the entire Australia tour sold out in three minutes.

"I started to cry when I found out we had tickets," 16-year-old Hannah said.

"One Direction are the full package, really.

"They look good, can sing and are entertaining."

Fifteen-year-old Veronica said it was the first band she had really loved.

"They just do their own thing, they are all about the music and the fans," she said.

The British boy band, based in London, is made up of Niall Horan, Zayn Malik, Liam Payne, Harry Styles and Louis Tomlinson.

They rocketed to fame after finishing third in the seventh series of the British X-Factor in 2010. They entered the competition as soloists and were put into a band by Simon Cowell.

The young crooners are famed for having the most fanatical fans in the business.

"Last time they were here I stalked them around Brisbane," Hannah said.

"I got to see Harry at his hotel and he waved at us…it was up there as one of the best moments of my life."

The girls said they would definitely be out and about in Brisbane on Saturday, October 19 - the day of the first concert - trying to catch a glimpse of the heartthrobs.

When asked what she would do if she got to meet the band, Veronica's answer was simple.

"You'd find me in hospital the next day," she said.

The girls said true 'Directioners' were not really supposed to have a favourite member of the band.

"You are supposed to love them all equally, but I do have a soft spot for one," Hannah said.

"It changes but it is Harry at the moment."

Veronica is less flexible.

"Mine is Harry," she said.

The girls said they do not know if their passion for the band would stick with them for years to come.

"I think we will tell our children 'Well, kids, they were the Beatles of our day'," Veronica said.
