Is a disclosure duty a weaker requirement than a stated minimum?

They are different kinds of requirement rather than a strict hierarchy of one being weaker. A stated minimum sets a floor on the size of cover; a disclosure duty sets an obligation about what the client is told. Failing either one is a compliance failure in its own right.

If the ACT names no minimum, does that mean an ACT contractor could hold very little cover and still comply?

The disclosure duty does not itself set a floor on the amount of cover held — its compliance question is whether accurate disclosure was made to the client, not whether the amount clears any particular bar.

Does a disclosure-duty jurisdiction still expect a certificate of currency to exist?

Disclosing insurance to a client is generally easier to do accurately with a certificate in hand, and a client asking to see one is a reasonable request even where the regulator itself is not checking a specific figure.

When a licence names an amount, and when it names a duty

In short

Most jurisdictions that condition a licence on insurance do it the same way: they name a minimum figure the cover has to meet, checked against the licence.
The ACT does something structurally different for construction services: it makes insurance a disclosure duty owed to the client, with no minimum figure named at all.
The two mechanisms answer different questions — a stated minimum answers "is the cover big enough," a disclosure duty answers "does the client know what is actually held" — and satisfying one says nothing about the other.

When most people picture an insurance condition on a licence, they picture a number: a minimum limit that has to be met before the licence is granted or renewed. That is the common pattern across Australian building trade licensing, but it is not the only one, and the exception is worth understanding on its own terms rather than treated as a lesser version of the number-based approach.

This page sets out the difference between the two mechanisms directly, using the ACT’s disclosure-based approach as the clearest example of the second kind.

The amount-based mechanism

A stated-minimum condition works by setting a figure — a limit of cover a licence holder has to carry — and checking the licence holder’s certificate against it. The regulator’s job is comparative: does the number on the certificate meet or exceed the number in the regulation. This is the mechanism behind most of the fixed-minimum conditions described elsewhere on this site, including the majority of state electrical contractor conditions.

It is a mechanically simple check, which is part of why it is the most common approach — a certificate either states a limit that clears the bar or it does not, and the comparison does not depend on anything else about the relationship between the contractor and the client.

The duty-based mechanism

A disclosure duty works differently. Rather than setting a number the regulator checks, it places an obligation on the licensee to tell the client what insurance is actually held before the work begins. The ACT applies this general approach to construction services, and it applies specifically to electrical licensing there instead of a stated minimum.

Under this model, there is no figure a licence holder has to clear to be compliant. The compliance question is whether the disclosure was actually made, accurately, before the client engaged the contractor — a process obligation rather than a coverage-size obligation.

Why the two are not interchangeable

A contractor holding a policy that would satisfy a fixed-minimum state’s condition has not automatically satisfied a disclosure duty, because the duty is about telling the client, not about the size of the policy. Equally, a contractor who has disclosed their cover accurately under a duty-based regime has not necessarily met a fixed minimum, because no minimum was ever named to meet.

This matters most for a contractor moving between the two kinds of jurisdiction, or bidding on work in both. Assuming a disclosure regime is just "a softer version" of a minimum, or that a minimum regime is "the same idea, just also written down," gets the compliance question wrong in both directions.
