What Past Offences Are Shown on a Nationally Coordinated Criminal History Check?

A spent conviction is an older conviction that may no longer need to be disclosed after a set period without further offending. In many cases, it will not appear on a Nationally Coordinated Criminal History Check, helping people move forward without being unfairly affected by minor past mistakes. However, some roles, industries, and purpose codes can still require broader disclosure.

What Is a Spent Conviction?

Under Australian spent convictions laws, certain older or less serious convictions may stop appearing on a Nationally Coordinated Criminal History Check after a set crime-free period. This is designed to support rehabilitation and allow people to move forward without an old mistake creating unnecessary barriers.

In many cases, the process is automatic and a separate application is not required. Once the relevant period expires, the conviction is generally excluded from the result, depending on the applicable Commonwealth, state, or territory rules.

Important: Spent convictions do not disappear in every circumstance. Some roles, disclosures, and legislative exceptions may still allow or require access to certain spent conviction information.

Key Points About Spent Convictions

  • Automatic in some cases: You may not need to apply for a conviction to become spent. In many jurisdictions, it is excluded automatically once the qualifying period ends.
  • Not every offence becomes spent: Serious offences, including some sexual offences or offences resulting in longer prison sentences, are often excluded from spent conviction schemes.
  • Disclosure depends on purpose: The type of Nationally Coordinated Criminal History Check, the role, and the purpose code can affect what information is released.
  • Higher-trust roles can involve broader disclosure: Roles involving children, aged care, security, intelligence, law enforcement, or classified access may involve exceptions.

Why Purpose Codes Matter

A Nationally Coordinated Criminal History Check does not always disclose the same level of information for every application. The purpose code helps determine what categories of offences may be released and whether only unspent offences or a broader set of records may be disclosed.

This is especially important in the Australian Capital Territory (ACT) and for Commonwealth employment and screening purposes, where specific codes may result in different disclosure outcomes.

Working in the Australian Capital Territory (ACT)

For certain ACT roles, Nationally Coordinated Criminal History Checks may release more than just unspent offences. The exact disclosure depends on the relevant ACT purpose code and category.

Commonwealth Employment and Purpose Codes

Commonwealth-related Nationally Coordinated Criminal History Check purposes may also change what is disclosed. Some categories release only unspent offences, while others may permit disclosure of all Commonwealth offences and additional state or territory information where legislation allows.

Pre-Employment and Standard Disclosure

For general employment and standard disclosure purposes, the scope is usually narrower and often limited to unspent offences, subject to Commonwealth, state, and territory legislation.

What This Means for Applicants

A spent conviction will often not appear on a standard Nationally Coordinated Criminal History Check, but there are important exceptions. The result can change depending on the role, the industry, the employer's screening purpose, and the specific purpose code used for the application.

  • General employment: Often limited to unspent offences only.
  • Children, aged care, disability care, or security roles: May permit broader disclosure.
  • Commonwealth and overseas purposes: Can involve wider release rules depending on legislation.
  • ACT regulated roles: May disclose all ACT offences for certain categories.
