Meet the couple that gives free sex show to public from balcony!

A couple in Australia is gaining notoriety by performing sex acts in broad daylight and in full view of people in their balcony of Darwin's La Grande apartments

The Northern Territory pair are said to sip on champagne and smoke cigarettes before putting on a free sex show six stories up in the middle of the city.

One office worker suggested the couple had publicly displayed their intimate affection for each other before.

"It's the first time I've seen it but a few of the other ladies said they have seen it before," the Herald Sun quoted her as telling the NT News.

"I don't know if it was the same couple, though.

"All the girls at the window just erupted in laughter so the whole floor walked across and saw it.

"We all were thinking 'far out, please just take it inside'."

She said the show "made for a good afternoon", she added.

Last year, a survey of more than 10,000 men and women revealed almost every second Northern Territorian enjoys having sex in public - from beaches to bathrooms, offices to nightclubs.
