It follows, in my view, that to prove the statutory crime created by s 233B(1)(b) of the Customs Act, of attempting to import prohibited imports into Australia, the Crown must prove that the accused at all material times intended to import something which was as a matter of law a prohibited import and known by him to be so, and that pursuant to this intention he did an act or acts (including omissions) not merely preparatory but sufficiently proximate to the intended commission of the crime.
In this case, the false bottom in the suitcase, the secreting therein of packets containing a powdery substance, the consignment of the suitcase from Turkey to Melbourne, the failure to declare the packages believed by the accused to be cannabis, the collection of the suitcase from the carousel, all provide sufficiently proximate acts to constitute the actus reus and to manifest the intention to import a prohibited import. Cannabis is as a matter of law a prohibited import within the meaning of s 233B(1)(b). The accused admits that he intended to import cannabis. He stated that he knew that he had 'made one big mistake' and that he was 'prepared to suffer the consequences'.
If these matters are proven, there is established both the mens rea (the intention to import a known prohibited import, cannabis) and the actus reus (sufficiently proximate unequivocal acts or omissions) of the crime of attempting to import a prohibited import, namely cannabis.
... Attempts are not to be confined to acts which if not interrupted would result in the commission of the crime itself.
Attempts are crimes because of the criminal intent of the actor. A man who intends to kill V, and who picks up a gun believing it to be loaded, and who points it at V and pulls the trigger is guilty of an attempt to murder V, even if it transpires that the gun was not loaded. Why is this an attempt? Because if the facts had been as the actor believed them to be, he would have committed the intended crime; he intended to murder V, but failed because of a mistake of fact. He is punishable for an attempt, not because of any harm that he has actually done by his conduct, but because of his evil mind accompanied by acts manifesting that intent. The criminality comes from the conduct intended to be done. That conduct intended must amount to an actual and not an imagined crime, but if it does, then it matters not that the gun is in fact unloaded, or the police intervene, or the victim is too far away, or the girl is in fact over 16, or the pocket is empty, or the safe is too strong, or the goods are not cannabis.
