Melbourne, July 3 Brothels in Australian city of Perth are putting on more staff to deal with the arrival of two US warships, carrying more than 5400 sailors.

Nuclear powered aircraft carrier USS George Washington and guided missile cruiser USS Cowpens docked off Fremantle yesterday.

According to business groups estimates, the sailors' arrival will boost the local economy by 5 million dollars during the ships' five-day stay.

Beverly Clarke, the owner of Perth brothel Langtrees, said that she had put on five extra staff for the weekend, including two from the eastern states.

Although the business had already been boosting up a little, she was quite positive that the numbers would increase markedly by tonight.

"Two more (US) sailors just walked in. At the moment I've even got girls from the eastern states here to assist us," News.com.au quoted her as saying.

A spokeswoman for another brothel Maddison Avenue said that they were preparing for a busy weekend.

"We'll find out tonight (if we are busy). We've got all staff rostered on and a couple of more girls than a normal Friday night," said the spokeswoman. (ANI)
