The Act revolves around a compact of data-collection authority, publication discretion, compulsory information-gathering powers, secrecy obligations, and inter-governmental arrangements. Those concepts operate through specific, short provisions.
Scope of statistics: Section 4(1) lists three principal areas the Secretary may cover: the loading/unloading of cargo to and from ships, the loading/unloading of cargo to and from vehicles at a port where that cargo relates to ships at the port, and the movement of ships into, from or within ports. Each of the first two heads specifically includes statistics about employment in or in connection with the loading/unloading and the availability of persons for such employment (s 4(1)(a)(i)-(ii) and s 4(1)(b)(i)-(ii)). These enumerated topics are the Act’s substantive reach; any collection beyond those matters would not be authorised by the text supplied.
Publication and identification constraints: The Secretary has broad discretion to publish or make available collected statistics “in such manner as he or she thinks appropriate” (s 4(2)). That discretion is constrained by a prohibition on publishing statistics in a way that enables identification of a particular person or organisation (s 4(3)). The Act, however, creates an explicit exception: if it is not practicable to publish statistics without enabling identification, the Secretary may publish them in an identifiable form (s 4(4)). The Act does not define “practicable” or prescribe a test for identifiability; it leaves those judgements to the Secretary's exercise of discretion.
Compulsory information powers and limits: Section 5 authorises the Secretary to require persons, by written notice, to furnish specified information or to produce specified books or documents “within such reasonable time and in such manner as is specified in the notice” (s 5(1)). Critically, subsection 5(2) limits the power to require production of books or documents to situations where the Secretary needs to verify the accuracy of information already furnished under s 5(1)(a). Thus, the Act draws a line between information notices and document production, making the latter conditional and narrower in scope.
Criminal law overlay: The Act makes Chapter 2 of the Criminal Code applicable to its offences (s 3A), and the notes to s 5 indicate that strict liability applies to the offence of failing to comply with a requirement under s 5(1) (s 5(5) and note), and that a defendant bears an evidential burden regarding the defence in s 5(4) (note). The Act therefore marries its compliance offences to the general principles of criminal responsibility in the Criminal Code.
Secrecy: Section 7 imposes confidentiality obligations on officers who acquire information under the Act. The prohibitions extend to making records, divulging information acquired in the course of duties, and producing documents furnished for the Act’s purposes, subject to authorised disclosures and the regulations (s 7(1)). The penalty for breach is imprisonment for three months or 10 penalty units (s 7(1) penalty provision). The definition of “officer” in s 7(4) is broad and the section explicitly extends to State officers (s 7(5)). Section 9 creates a specific carve-out allowing disclosure to the Australian Statistician (ss 9(2)-(3)).
Delegation and intergovernmental arrangements: The Secretary may delegate his or her powers (other than the power to delegate and powers under s 8) by written instrument (s 6(1)). Delegated powers, when exercised by a delegate, are deemed to have been exercised by the Secretary (s 6(2)), and the Secretary may still exercise the power notwithstanding the delegation (s 6(3)). Separately, the Minister may enter into arrangements with State Ministers about delegation to State officers and authorities and the supply of information both to and from States (s 8).
Regulation-making and other Acts: The Governor‑General may make regulations not inconsistent with the Act for carrying out its purposes (s 10). Section 9(1) preserves the Australian Statistician’s functions under the Census and Statistics Act 1905, and s 9(3) treats information furnished to the Australian Statistician under s 9(2) as having been furnished under the Census and Statistics Act for the purposes of that Act.
Collectively, these concepts give the Secretary and Minister practical instruments to collect port-related statistics, to seek necessary information and documents, to limit and manage disclosure, and to partner with State authorities and the Australian Statistician. The Act leaves substantial operational detail to the Secretary’s judgment and to regulations that may be made under s 10.
