A member of a Chinese delegation to Melbourne has been charged with raping a university student tour guide assigned to his group.

Jingsong Song, 43, the head of a Chinese government urban planning institute, has been reporting daily to police in Melbourne since his arrest and extradition from NSW three months ago.

Song was bailed in August, on strict conditions that included surrendering his passport with orders he not leave Victoria or Australia, on charges that included two allegations of digital rape.

He appeared in Melbourne Magistrates Court on Thursday to apply to vary his bail to allow his return to China, to report daily in Guangzhon City and return once a month to Victoria.

Magistrate Donna Bakos heard Song was also prepared to put up a $500,000 cash deposit and two friends a total of $150,000 in sureties to help ensure he answered his bail.
