There were lines out the door at Dickson Newsagency on Monday afternoon as scores of hopefuls queued for their chance at winning the $100 million OzLotto jackpot today.

Newsagency co-owner Andrew Nuttall said the store had more than 2000 customers last Tuesday when the jackpot was $70 million, and he had rostered on extra staff today to deal with the demand.

''We had a huge week last week. It was extremely busy,'' he said.

Mr Nuttall said he had seen regulars and new customers alike come in for their ticket, spending about $20 on average.

''It's across every single walk of life, every single person will be having a crack at it,'' he said.

Some of those in the queue at Dickson Newsagency said they regularly bought OzLotto tickets, while others were first-time players.

When asked what they would do with $100 million should they win, common responses included buying a house or car, helping out family or giving the money to charity.

One young woman said she would ditch plans to go to university or work in favour of sleeping all day.

Mr Nuttall said despite the low margins on lottery tickets for proprietors, it was great to have so many customers in the shop, and while the laws governing the lottery meant he could not buy a ticket at his own store he was planning to purchase one elsewhere if he got the chance.
