Parents' outrage at an advertisement for a swingers party at a Cranbourne children's play centre has forced the local council to close the business.

The advertisement for a party this Saturday featured pictures of sex acts and nude photographs of the centre's owners, who said they would repeat the event every month at Casey Kids Playhouse once they found six other couples.

The offending advertisement.

The notice was placed on several websites, including Craigslist, and another version showed the couple in bathers and embracing fully clothed.

Both advertisements said the ''party venue (not a home) has many features like a laser light show, fog machine, great sound system, games, a giant ball pit and a jumping castle, and an awesome time will be had by all''.
