Man charged

The victim is believed to be a nine-year-old girl who went missing from the Blue Mountains near Sydney last Thursday, local media report.

The child's body was found by officers on Tuesday during a search of bushland in a neighbouring area.

Police said a 31-year-old man had been arrested in a flat in inner Sydney and charged with murder.

He was remanded in custody to face a court on Wednesday.

Media reports said the girl - who cannot be identified for legal reasons - was on holiday with her mother when she disappeared last Thursday.

Currently on bail, he has been charged with making a false declaration on a travel document.

The case is considered historical, presenting a low risk to the public.

Health Secretary Bob Williams says the man arrived in Auckland from Egypt on 5 May, where he tested positive for the virus in managed isolation.

He tested negative before being released from quarantine after which he flew to the Cooks, where he tested positive on 5 June.

All his close contacts have tested negative.
