shall be guilty of an offence.
(1A) On the prosecution of a person for an offence against the last preceding sub-section, being an offence to which paragraph (c) of that sub-section applies, it is not necessary for the prosecution to prove that the person knew that the goods in his possession or of which he attempted to obtain possession had been imported into Australia in contravention of this Act, but it is a defence if the person proves that he did not know that the goods in his possession or of which he attempted to obtain possession had been imported into Australia on contravention of this Act.
(1C) Any defence for which provision is made under either of the last 2 preceding sub-sections in relation to an offence does not limit any defence otherwise available to the person charged.
(2) The prohibited imports to which this section applies are prohibited imports that are narcotic goods….
(3) A person who is guilty of an offence against sub-section (1) of this section is punishable upon conviction as provided by section 235….
11 Section 235 of the Act contains provisions dealing with the maximum penalty prescribed for an offence under s 233B. It relevantly provides:
(1) …..
(2) Subject to sub-sections (3) and (7), where:
(a) a person commits an offence against sub-section 231(1), section 233A or sub-section 233B(1); and
(b) the offence is an offence that is punishable as provided by this section,
the penalty applicable to the offence is:
(c) where the Court is satisfied:
(i) that the narcotic goods in relation to which the offence was committed:
(A) are a narcotic substance in respect of which there is a commercial quantity applicable; and
(B) consist of a quantity of that substance that is not less than that commercial quantity; or
….
a fine not exceeding $750,000 or imprisonment for life, or both or for such period as the Court thinks appropriate;.

12 As was noted in the joint judgment of Gleeson CJ, Gummow and Hayne JJ in Cheng at [25] in relation to an offence under s 233B(1)(d) of being knowingly concerned in the importation into Australia of prohibited imports, an offence under s 233B(1)(c) does not require that a person have knowledge of the amount of the prohibited import which he possesses or attempts to possess before he can be convicted of the offence set out in the section. An offence is committed under paragraph (c) if the person, without reasonable excuse, attempts to obtain prohibited imports to which the section applies, being in the present case narcotic goods. There is nothing in any of the provisions of s 233B that refers to an amount of narcotic goods. No mention is made of quantities until one comes to s 235.
13 It was held by five Justices in Cheng that knowledge or belief of the quantity of the narcotic goods the subject of an offence under s 233B(1)(d) was not an element of the offence created by that section. The majority of the Court, applying Meaton was of the view that s 235 created no offence in relation to a particular quantity of narcotic mentioned in the section but that the section was merely prescribing the maximum penalty in relation to an offence under s 233B depending upon the quantity of the narcotic goods involved in the offence and their nature. Only Justices Gaudron and Kirby were of the opinion that either a combination of the two sections (per Gaudron J) or the terms of s 235 alone (per Kirby J) created discrete offences depending upon the amount of the narcotic goods alleged. The outstanding issue left unresolved by the decision in Cheng was the validity of s 235 in light of s 80 of The Constitution and the decision in Kingswell. That issue was further considered in the recent decision of Cheung v The Queen [2001] HCA 67.
14 It would seem to me that, on the face of it, the reasoning of the majority of the High Court in Cheng in relation to an offence under s 233B(1)(d) should apply with equal force to any of the offences contained in the section and in particular to an offence under s 233B(1)(c). I see no reason in logical or legal principle to hold that the mental element relevant to the existence of narcotic goods, or their nature or quantity, should vary depending upon what particular category of offence under s 233B is being considered. One might ask rhetorically why Parliament should have intended such a result? This is particularly so in respect of an offence under s 233B(1)(c), where it is unnecessary for the Crown to prove that the accused knew that the narcotic goods in his possession, or in respect of which he attempts to obtain possession, had been imported.
15 In He Kaw Teh v The Queen (1985) 157 CLR 523 at 584-586 Brennan J held that for an offence under s 233B(1)(b) and (c) it is sufficient if the Crown proves that the accused knew or believed of the existence of narcotic goods even if he was unaware of the nature of the narcotic goods. The decision in Kural v The Queen (1987) 162 CLR 502 proceeds on the same basis. The maximum penalty prescribed under s 235 differs depending upon whether the narcotic goods were cannabis or not. Whether the quantity of narcotic goods amounts to a commercial or trafficable quantity and, therefore, what maximum penalty is applicable to the offence committed depends upon the nature of the narcotic goods. However, notwithstanding that the nature of the narcotic goods imported can have a very significant impact upon the sentence to which the offender is liable, proof of knowledge or belief of the nature of the narcotic goods is not required for proof of an offence under the section. If the accused's knowledge of the nature of the narcotic goods imported is irrelevant to proof of an offence under s 233B(1)(c) or the maximum penalty applicable, I find it difficult to understand why the Crown should be required to prove knowledge or belief of the amount of the narcotic goods imported.
16 However, the argument in support of the applicant is that, because the offence alleged in the present case is an attempt committed in circumstances in which it was impossible to perform the completed offence, the situation is different and the elements of the offence change so that the Crown is required to prove the knowledge or belief of the accused as to the quantity of the drug which had been imported and in respect of which he sought to obtain possession. Again I confess that I do not understand why such a result should follow as a matter of logic or policy. Why, I ask myself, should it matter on the issue of the accused's guilt of an offence under the section that the Customs officers intercepted the drug and removed it before the accused could obtain possession of it? Would it be relevant that there was some other obstacle in the way of the accused obtaining possession of the narcotic goods which had been imported, for example if the narcotic goods were in the possession of a Custom's officer who never intended that the accused would obtain them even though the accused did all that was necessary on his part to come into possession of them? What if the drugs had been lost or inadvertently destroyed by the importing agency after being imported but before the accused could collect them?
17 But the criminal law does not always work with logical precision and the interaction of statute and the common law sometimes produces surprising or at least unexpected results. It is, therefore, necessary to consider in some detail what is said to be the authority for the result for which the applicant contends: the judgment of Hunt CJ at CL (as he then was) in Mai.
18 That was an appeal from a conviction for offences under the very same provision as is presently being considered. The appellant Mai was convicted of two offences, one of being in possession of portion of the drug imported and an offence of attempting to obtain possession of some other part of the drug. Unlike the applicant before the Court, in respect of the charge of attempt to obtain possession Mai had been charged with attempting to obtain possession of an identifiable part of the heroin imported. It is necessary to briefly refer to the facts to understand the charges and this Court's decision. The charge of possession arose from the discovery by Federal police of thirty blocks of heroin in a suitcase that had arrived by air as unaccompanied luggage. The police substituted for those blocks thirty blocks of plaster of paris, some of which contained a small amount of heroin as a controlled delivery. The suitcase was left at the airport in the hope that someone would collect it, but no one did. It was then taken to a room in a motel at Ultimo but again it was not collected. It was then moved to a motel at Bondi.
19 A man named Tran eventually came to the room at that motel and attempted unsuccessfully to open the suitcase. He then left the room and spoke to Mai. Tran then returned to the room, picked up the suitcase and took it to a motor vehicle in the boot of which he placed the suitcase. When he was arrested some time later, a number of the blocks were found in a sports bag in the vehicle, two of the blocks containing a small amount of the heroin actually imported. The suitcase was found in the premises of a former girlfriend of Mai, where he had resided at one time. There was other evidence linking Mai with the suitcase. Mai was later arrested and found to have one of the substitute blocks in his possession. That block contained no heroin at all. However, his possession of that block was the basis of the charge of attempting to obtain possession of the block of heroin for which the block of plaster of paris had been substituted. The offence charged in respect of this block was an attempt to obtain possession of a quantity of narcotic goods being not less than the trafficable quantity applicable to heroin. Mai was convicted of that offence. He was also charged with possession of the thirty blocks that had been placed in the suitcase by police based upon a common purpose to possess them with Tran. He was also convicted of that offence.
20 On appeal, Mai argued that he could not lawfully be convicted of attempt to have possession of narcotic goods in a situation where it was physically impossible for him to have obtained possession of those goods. The argument with which this Court was principally concerned was whether the decision of the House of Lords in Haughton v Smith [1975] AC 476 should be applied to an offence under the Customs Act. It is unnecessary to repeat the arguments that led the Court to hold that it should not follow the House of Lords but rather should apply decisions of the Full Court of Victoria and the Court of Criminal Appeal of Western Australia in Britten v Alpogut [1987] VR 929 and Lee (1990) 47 A Crim R 187. Mai has frequently been applied in this State and its correctness is not presently in doubt.
21 Hunt CJ at CL with whom the other members of the Court agreed stated (at 381G-382C):
"I interpret the law laid down in Britten v Alpogut (and adopted in R v Lee ), when applied to the general law of attempt, as being that, in circumstances where it is in fact physically impossible for the accused to commit a particular crime, an attempt to commit that crime has nevertheless been proved if the Crown establishes:
