A 48-year-old man has been charged by police investigating suspicious packages delivered to embassies and consulates throughout Australia.
The British consulate in Melbourne was one of 38 to be sent parcels, with officers continuing to test them to determine what substance they contain.
Police have recovered 29 of the packages and have said there is no ongoing threat to the public.
The man from Shepparton, more than 100 miles north of Melbourne, is due before magistrates in the Victorian capital on Thursday.
The Australian Federal Police said: “The man was arrested at his home last night and was charged with sending dangerous articles to be carried by a postal service, contrary to section 471 of the Criminal Code Act 1995.”
