The former Hey Dad..! star was detained by police over allegations he indecently assaulted a number of young girls in Australia between 1985 and 1990.
The 63 year old, who maintains his innocence, appeared at Westminster Magistrates' Court on Thursday (09Aug12) and was granted $96,000 (£60,000) bail under the provision that he wears an electronic anklet and stays away from children under the age of 16.
Australian officials are expected to apply for an extradition order to bring Hughes back Down Under to answer the charges.
A hearing related to the extradition process will take place in London on 19 September (12).
New South Wales Sex Crimes Squad Detective Superintendent John Kerlatec told reporters in Sydney that the arrest came after a long and intensive investigation by Australian police working in co-operation with detectives in the U.K.
He says, "More than 200 people have been interviewed. It's been an exhaustive investigation... My objective is to ensure that, at some point in time, Mr Hughes appears in court in New South Wales... to allow the witnesses and victims to have their time in court."
Hughes, who played Martin Kelly in the popular Aussie sitcom from 1987 until 1993, has been accused of 11 sexual and indecent assault offences. He faces up to 10 years in prison if convicted.
