Justices of the Peace by the numbers

A large amount of Australian administrative life runs on the unpaid work of Justices of the Peace. Every mortgage discharge, insurance claim, change of name, visa support letter and progress claim that needs a witness is, in the ordinary case, witnessed by a volunteer who is not paid for it and who did not have to say yes.

It is worth setting out what the published figures actually show, because the picture is less uniform than most people assume, and because the numbers are interesting in their own right.

The headline figures

The clearest comparison available comes from a question on notice asked in the Victorian Legislative Council on 9 September 2025. The per-capita figures were put by the member asking the question; they are not a government count, and no state register publishes one. On those figures:

State	JPs per 100,000 people
Queensland	approximately 1,432
New South Wales	approximately 893
Victoria	approximately 50

The Attorney-General's answer, given on 27 October 2025, put Victoria's registered cohort at 3,667 Justices of the Peace.

The Queensland-to-Victoria ratio is close to thirty to one on a per-head basis. That is not a rounding difference or a definitional quibble at the margins. It is two states of broadly comparable development running entirely different systems.

What the gap actually reflects

The obvious reading — that Victorians are less willing to volunteer — is almost certainly wrong, and it is worth saying so directly before the number does any unearned work.

The states have made different structural choices.

Queensland maintains a very large volunteer cohort, and it has two offices rather than one: Justices of the Peace and Commissioners for Declarations. The Commissioner for Declarations role is a narrower appointment focused on witnessing documents, with a correspondingly lighter qualification burden, and it substantially widens the pool. Queensland also runs a well-developed network of signing sites.

New South Wales has a large appointed cohort and an official public register, with JPs commonly attached to councils, courthouses, libraries and community organisations.

Victoria runs a smaller appointed cohort supported by a documented network of scheduled signing services — sessions at known places at known times, which people attend by appointment or during published hours. Fewer people, arranged differently.

A per-capita count measures appointments. It does not measure how easy it actually is to get a document witnessed, which depends on where those people are, when they are available, and whether the system is designed around a register or around scheduled sessions.

What the numbers do not tell you

Three things worth keeping in view, because they are the questions the headline figures invite and do not answer.

Distribution, not just count. A state-wide per-capita figure says nothing about whether a particular postcode has anybody. Remote and outer-regional coverage is a different question from state-wide density, and the aggregate can look healthy while a specific town has nobody within an hour.

Availability, not just appointment. A person on a register is not a person available at four o'clock on a Sunday. Signing services run at published times, and those times are, understandably, the times volunteers can give: business hours, weekday afternoons, Saturday mornings.

Age and succession. Commentary on volunteer registers across a range of fields often raises the question of an ageing cohort and replacement rates. We have not seen published data that would let us say anything useful about that for JPs specifically, and we are not going to infer it from a total.

We have set out the figures as published, with their sources. We have not extrapolated a trend from them, because a single set of per-capita counts does not support one.

What this means if you need a document witnessed

For most documents, a Justice of the Peace is sufficient, free, and the right answer. That is worth saying plainly on a page belonging to a business that charges for witnessing.

A JP falls within the authorised witness class for the great majority of statutory declarations and affidavits in the state of their appointment. If you can reach one during the hours they sit, you should, and you should not pay anybody for what a volunteer will do properly for nothing.

The practical questions are the ones the per-capita figures do not reach:

• Is there one near you? Check your state's official register or signing-service timetable first.
• Can you get there when they sit? Signing sessions keep the hours volunteers can give, and those are usually business hours.
• Is your deadline compatible with those hours? Month-end progress claims, tribunal filing dates and settlement timetables do not move to suit a Tuesday afternoon session.
• Is the JP within the authorised class for your particular document? For the ordinary case, yes. For a document made under another jurisdiction's law, check.

Where we fit

We are an alternative on availability, not on authority.

An Australian legal practitioner is within the authorised witness class in every Australian jurisdiction, which removes any question of eligibility for an unusual document. That is a real convenience, but it is not a claim that a practitioner witnesses a declaration better than a JP does. The process is identical and the legal effect is identical.

What differs is when. A volunteer signing service at a library counter closes when the library closes. We witness on weekday lunchtimes and evenings and through the day at weekends, because the demand that cannot be met by the free option is overwhelmingly demand that arrives after five o'clock or at a weekend.

If the counter is open and you can get to it, go. If it shut an hour ago and the claim is due tomorrow, that is the gap we exist to fill.

This note is general information. The figures quoted are reported as published by the sources listed, current as at the date shown, and have not been independently recalculated. Official state registers are the authoritative source for JP numbers, appointments and signing service times.
