The car driven by John Hunter is a Ford Mustang that was imported especially for the series, as the model was uncommon in Australia at the time. The vehicle's registration number is JOH 999, which is a genuine Victorian registration. The letters in this registration are for John Hunter and the number was chosen to signify the Nine Network.
This man wears no uniform. He has no rank. His name is often not his own. The law offers him no special protection, no exemption. If necessary, his own country will deny his existence. He is part commando, part detective, part spy. He is Hunter.
