Marine Insurance Act 1909

The Act applies to marine insurance other than State marine insurance, and to State marine insurance that extends beyond the limits of the State concerned (section 6(1)). It does not apply to contracts made before its commencement (section 6(2)). It applies to insurers writing marine cover (including Lloyd's syndicates and London market underwriters writing Australian risks), to the assured (commonly shipowners, charterers, cargo interests, marine warranty surveyors, and protection and indemnity clubs), to brokers and underwriting agents, and to anyone with an insurable interest in a marine adventure (section 11).

Mutual insurance arrangements are also within the Act, with modifications. Section 91 allows the provisions of the Act, except for any provision relating to premium, to apply to mutual insurance, subject to modification by the policy or rules of the association.

The interaction with the Insurance Contracts Act 1984 (Cth) is decisive: a contract to which the Marine Insurance Act applies is excluded from the Insurance Contracts Act. That allocation matters because Insurance Contracts Act remedies, particularly section 54 which can defeat refusal to pay based on conduct that did not cause the loss, are not available where the policy is a marine policy.

The assured must disclose every material circumstance known to them, or which in the ordinary course of business ought to be known to them, before the contract is concluded (section 24). A material circumstance is one which would influence the judgment of a prudent insurer in fixing the premium or determining whether to take the risk. Failure to disclose entitles the insurer to avoid the contract.

Representations made by the assured or the assured's agent during negotiation must be true (section 26). A material representation must be substantially correct.

Warranties must be exactly complied with (section 39(3)). The implied warranty of seaworthiness in section 45 applies in a voyage policy; in a time policy the corresponding obligation is narrower (section 45(5) provides that the assured is liable for any loss attributable to unseaworthiness only where the ship is sent to sea in an unseaworthy state with the privity of the assured).

The contract must be embodied in a policy (section 28), and the policy must specify the matters set out in section 29, including the name of the assured, the subject-matter, the risk insured against, the voyage or period of time, the sum or sums insured, and the name of the insurer.

The premium must be paid as agreed (Part IV). Failure to pay the premium does not, of itself, prevent the policy from coming into force, but it gives rise to remedies in the insurer including avoidance and recovery of premium (section 58 and the rules in Part VII for return of premium).

The Act is largely a code of substantive rules rather than a regulatory regime, so it confers few discretionary powers on a regulator. Power lies with the parties and with the courts construing the contract.

The court has power to declare a policy void as a wagering or gaming contract under section 10, to declare a contract avoided for breach of the duty of utmost good faith under sections 23 to 26, and to determine the construction of the policy by reference to the rules in the Second Schedule (section 36).

The court fixes the date of breach of warranty under section 39(3), determines whether a deviation has occurred and whether it is excused under section 55, and decides whether a constructive total loss has occurred under section 66. The court rules on subrogation rights of the insurer under section 85 and contribution between insurers under section 86.

The Marine Insurance Act creates no offences and contains no civil penalty provisions. Its enforcement is through ordinary contract law. The two principal remedies are avoidance and discharge: avoidance for non-disclosure, misrepresentation, breach of utmost good faith, or wagering, and discharge for breach of warranty (section 39(3)).

Recovery of indemnity is the assured's principal action. The action is brought against the insurer in the Federal Court or in a State or Territory Supreme Court exercising jurisdiction. The measure of indemnity in Part VI controls the quantum of recovery. Subrogation under section 85 entitles the insurer, after paying for a total loss, to step into the assured's rights against any third party responsible for the loss. Contribution between insurers under section 86 governs disputes among insurers where there is double insurance.

The contract is concluded when the proposal is accepted by the insurer (section 27). The contract must be embodied in a policy (section 28), but the cover note or slip may be referred to in evidence (section 95).

The risk attaches according to the type of policy. A voyage policy attaches at the commencement of the voyage (section 31). A time policy attaches for the period of time specified (section 31). The implied warranty of seaworthiness under section 45 must be satisfied at the commencement of the voyage and, where the policy attaches while the ship is in port, at the commencement of the risk.

Notice of abandonment is the gateway to a constructive total loss claim (section 68). Where the assured elects to abandon the subject-matter to the insurer in circumstances satisfying section 66, the assured must give notice of abandonment with reasonable diligence after receipt of reliable information of the loss; failure to give notice converts the claim into one for partial loss only.

Reasonable time, where the Act uses that expression, is a question of fact (section 94).

The Insurance Contracts Act 1984 (Cth) does not apply to a contract to which the Marine Insurance Act applies. This is a critical structural rule. It was central in Gibbs v Mercantile Mutual Insurance (Australia) Ltd [2003] HCA 39, where the High Court determined whether a marine pleasure craft policy was governed by the Marine Insurance Act, with the consequence that the relief available under section 54 of the Insurance Contracts Act for late notice was not available.

Section 4 preserves the common law and law merchant, except where inconsistent with the Act. The Schedule 2 rules for the construction of policy terms operate as part of the substantive law.

The Act intersects with maritime safety legislation, including (at the State level) instruments such as the Marine Act 1988 (Vic) and the Western Australian Marine Act 1982 (WA), where compliance with vessel survey, registration, and operating conditions is relevant to the implied warranty of legality under section 47 (illustrated by the analysis in Switzerland Insurance Australia Ltd v Mowie Fisheries Pty Ltd [1997] FCA 231).

The First Schedule lists Imperial and State Acts that do not apply to a contract of marine insurance to which this Act applies (section 5).

Time policies cut across the warranty of seaworthiness in section 45. Subsection (5) provides that in a time policy there is no implied warranty that the ship is seaworthy at any stage of the adventure, but if the ship is sent to sea in an unseaworthy state with the privity of the assured, the insurer is not liable for any loss attributable to unseaworthiness. Privity is a high bar, but actual knowledge of structural defect is enough.

The exact compliance rule in section 39(3) is harsher than in modern non-marine insurance. A breach of warranty discharges the insurer from liability as from the date of the breach, even if the breach is unrelated to the loss. Section 40 sets out the only excuses: a change of circumstances making the warranty inapplicable, the warranty being illegal, or waiver by the insurer.

Disclosure under section 24 runs to all material circumstances known to the assured or that ought to be known in the ordinary course of business. The standard is objective on materiality (would influence a prudent insurer), and breach entitles avoidance. There is no Insurance Contracts Act overlay.

The Insurance Contracts Act exclusion bites at the start of the analysis: if the policy is a contract of marine insurance, no statutory remedies under that Act are available. Whether the contract is one of marine insurance is a question of characterisation in light of section 7 and the policy as a whole.

Notice of abandonment is procedurally important. Failure to give notice with reasonable diligence converts a constructive total loss claim into a partial loss claim, with smaller recovery (sections 66 to 68).

Voyage and change of voyage are technical. Under section 51, where the destination is voluntarily changed after the commencement of the risk, the insurer is discharged from liability as from the time of change of voyage, regardless of whether the ship has actually deviated.

A shipowner takes out a voyage policy for cargo from Sydney to Melbourne with London market underwriters. Before the voyage commences, the master overloads the ship beyond its certified deadweight. The ship sinks. The implied warranty of seaworthiness in section 45 is breached at the commencement of the voyage; under section 39(3), the insurer is discharged from liability as from that date. The fact that the loss might also have been caused by an unrelated peril does not assist the assured.

A pleasure craft owner takes out a marine policy covering paraflying activities in protected waters of Western Australia with a navigation warranty. The owner conducts paraflying outside the certified protected waters. A claim arises. The threshold question is whether the policy is a marine insurance contract under the Marine Insurance Act 1909. If yes, the Insurance Contracts Act 1984 does not apply and there is no statutory relief for late notice or for breach of warranty. The High Court in Gibbs v Mercantile Mutual Insurance (Australia) Ltd [2003] HCA 39 dealt with exactly that characterisation question.

A cargo interest in goods being shipped from Eden in NSW to Portland in Victoria suffers a total loss. The cargo policy contains an express warranty regarding survey and manning. The assured fails to comply. The insurer raises section 47 (warranty of legality) and the express warranty of survey. The Federal Court considered this scenario in Switzerland Insurance Australia Ltd v Mowie Fisheries Pty Ltd [1997] FCA 231 and applied the section 47 implied warranty.

A yacht owner takes out a Lloyd's policy covering the period from departure from Australian waters until return. The yacht clears customs to leave but the loss occurs before clearance back into Australian waters on return. The carriage of "Period of Insurance" wording must be construed in the context of the Marine Insurance Act provisions on voyage and time policies (section 31), as discussed in Swashplate Pty Ltd v Liberty Mutual Insurance Company [2020] FCAFC 137.
