An interim control order has been placed on a Melbourne teenager who was accused of planning a bombing on Anzac Day, but later had all terrorism charges against him dropped.

The order, sought by the Australian federal police, puts heavy restrictions on Harun Causevic’s movements, requiring him to wear a tracking device 24 hours a day.

.............The man's lawyer Rob Stary told the court Causevic would plead guilty to three weapons offences, including possessing an AK-47 knife that police found under his bed.

He was also charged over with illegally possessing knuckle dusters, while another knife was found in a car.

The maximum penalty for the weapons charges is two years in jail, but Causevic's lawyers argued he should be given a good behaviour bond.

He was granted bail by the magistrate on the conditions he does not apply for a passport, does not attend any points of international departure and attends two separate counsellors for support.

Causevic, from Hampton Park in Melbourne's outer south-east, was the first Victorian to be held under a preventative detention order (PDO) when he was detained without charge following counter-terrorism raids in April.

Documents released by the Supreme Court in June showed Victoria Police used the PDO to hold Causevic, because of an alleged close association with terrorism suspect Sevdet Besim, and Numan Haider.

Haider was shot dead after attacking police with a knife in 2014.

Besim remains in custody after he was charged with conspiring to commit a terrorist act, and denied bail.

A third teenager, Mehran Azami, was not charged with terrorism-related offences, but remains in custody charged with 19 counts of importing weapons from a Chinese weapons importer........
