Several features of the Act create potential points of legal and practical uncertainty which users should spot and examine carefully.
"Notwithstanding any other Act or law" (s 5): The broadness of this phrase in s 5 gives Parliament’s authorisation primacy over other statutes to the extent the authorised works would otherwise conflict. However the Act does not specify which statutes are intended to be displaced beyond the Harbors Act and Crown Lands Act references in s 2. That wording may cause uncertainty about the extent to which regulatory regimes not mentioned are displaced or remain applicable. The Act does not state whether that notwithstanding primacy extends to common law remedies such as injunctive relief.
Exact siting "approximately as shown on the plan" (s 5): The authorised crossings and embankment are described as being in positions "approximately as shown on the plan in Schedule 4." The qualification "approximately" may create ambiguity over the permissible geographic variance from the plan. The plan itself (Schedule 4) is the statutory locational reference, but courts or regulators may be required to interpret how much deviation is allowed by the authorisation.
Plan dependence and plan content: The Act vests land and authorises works by reference to a plan in Schedule 4. The supplied text here does not reproduce the plan's graphic detail; the operative authority therefore depends on the actual Schedule 4 plan as attached to the Act. If that plan lacks precision, disputes may arise over boundaries and the precise area vested in fee simple under s 3.
Non-liability breadth (s 6): The phrase "shall not be liable for any costs, charges, compensation or damages whatsoever to any person whatsoever arising from or out of the said constructions" is extremely broad. Practitioners should note the Act purports to remove monetary liability "whatsoever" including in scenarios caused by "hindering or preventing navigation" or "diversion of waters." The Act does not address other forms of legal remedy such as injunctive relief or ancillary administrative remedies. The omission could lead to litigation testing whether equitable remedies remain available.
Permanent prevention of water access (s 5(c)): The Act contemplates a permanent embankment that would "permanently and completely prevent[] access by water between Angas Inlet and North Arm." That undertaking is described in absolute terms, which raises issues about existing or customary uses of the waterway, long-standing navigation rights or rights of public access. While s 6 removes financial compensation, other practical or regulatory consequences (for shipping, habitat, flood risk) are not addressed in the Act.
Absence of procedural protections or environmental requirements: The Act contains no express requirements for environmental assessment, public consultation, planning approval or mitigation measures within its text. That absence does not necessarily mean other environmental or planning laws are not relevant, but s 5's overriding language could be read to displace conflicting statutory processes. Practitioners should note that the Act does not expressly set out procedural safeguards.
Preservation of other Trust powers (s 7) alongside new powers: Section 7 preserves other rights or powers of the Trust, which could combine with the new authorisations to create broader operational scope than a narrow reading of the Act suggests. The combination of preserved powers, fee simple ownership and construction authorisations may give the Trust substantial unilateral authority over the site.
Withdrawal/resumption specifics: Sections 2(1) and 2(2) operate "Notwithstanding" provisions of earlier legislation to withdraw and resume specified reserves. The schedules reference historical proclamations and the Harbors Act of 1913 land acquisition. Practitioners should verify the exact identity and status of the parcels listed in Schedules 1-3, because those references are historical and may require archival or cadastral confirmation.
No express penalties or enforcement mechanisms: The Act imposes no explicit sanctions for non-compliance because it does not list duties that invite penal enforcement. That can be surprising when contrasted with the large-scale physical works the Act contemplates.
In sum, the key "gotchas" are the breadth of the notwithstanding and non-liability language, the plan-dependent and "approximate" siting, the absolute phrasing about permanent prevention of water access, and the Act’s silence on procedural and environmental safeguards. Each of those features points to potential disputes about interpretation, scope and the availability of remedies beyond monetary compensation.
