When conducting a criminal history check on a prospective employee, you may encounter terms that seem straightforward but carry significant legal weight: spent and unspent convictions. Getting this wrong – either by acting on a conviction you were never entitled to see, or by missing one that should have been disclosed – can expose your organisation to legal risk, reputational damage, or a serious safety incident.

This guide explains the difference, outlines your obligations as an Australian employer, and helps you understand that a thorough background check is not just good practice – it’s essential.

What Is a Spent Conviction?

A spent conviction is a criminal conviction that, after a legislated crime-free waiting period, no longer needs to be disclosed by the individual. In most circumstances, it will not appear on a standard criminal history check.

Think of it as a legal fresh start. Parliament recognised that people who have served their time and demonstrated rehabilitation deserve the opportunity to move forward without a past mistake defining their career forever.

How Does a Conviction Become Spent?

A conviction becomes spent automatically by operation of law – not by being deleted from the record. The individual must generally satisfy all of the following:

  • They have not reoffended during the relevant waiting period
  • The offence is not classified as a “serious” or excluded offence
  • The waiting period has elapsed (see below)
  • No court order has specifically prevented the conviction from being spent

Waiting Periods by Offender Type

Waiting periods vary slightly between states and territories, but the general national guide is:

  • Adults: 10 years crime-free from the date of conviction or release
  • Juveniles: 5 years crime-free from the date of conviction or release

Australia does not operate a single national spent convictions scheme. Rules exist at both Commonwealth level and within each state and territory, meaning obligations can differ depending on where the candidate was convicted and where the role is based. This is one of the key reasons why partnering with a specialist provider of background checks is so valuable – ensuring you’re applying the correct rules for each jurisdiction.

What Is an Unspent Conviction?

An unspent conviction is one that remains active on a person’s criminal record and must be disclosed to an employer when asked. A conviction remains unspent if any of the following apply:

  • The legislated waiting period has not yet elapsed
  • The offence is classified as serious or is otherwise excluded from being spent
  • The individual reoffended during the waiting period, resetting the clock
  • A court specifically ordered that the conviction cannot be spent

Critically, if a candidate fails to disclose an unspent conviction when directly and lawfully asked by an employer, this constitutes grounds for termination or withdrawal of a job offer – even if they are otherwise highly qualified for the role.

When Can Employers Ask About Spent Convictions?

This is where many employers make costly mistakes. In general, you cannot ask about or act on spent convictions during the hiring process. However, there are clearly defined exceptions across several sectors where the stakes are too high to allow any criminal history to remain hidden.

Spent convictions may still need to be disclosed in roles involving:

  • Working with children or vulnerable people (including aged care)
  • Healthcare, nursing, and clinical environments
  • Public transport and passenger-facing roles
  • Government positions and national security clearances
  • Roles involving access to firearms or dangerous substances

If your organisation operates in healthcare, aged care, or education, PBS offers sector-specific screening solutions for hospitals and clinical health providers, allied health professionals, and early childhood education and childcare settings – all designed to meet mandatory compliance requirements.

Why This Matters for Your Hiring Process

Most employers conduct background checks with the best of intentions, but without a structured process, it’s easy to inadvertently breach privacy legislation or – worse – miss a red flag that should have been caught.

Here’s what’s at stake if your vetting process is insufficient:

  • Legal liability: Acting on a spent conviction you were not entitled to receive can expose you to discrimination claims under Australian privacy and anti-discrimination legislation.
  • Reputational damage: A single high-profile incident involving an employee whose history was not properly checked can cause lasting damage to your brand.
  • Workplace safety: In roles involving vulnerable people, access to sensitive data, or financial responsibility, an undetected history of relevant offending is a genuine safety risk.
  • Negligent hiring claims: Courts have found employers liable for not taking reasonable steps to screen employees who later caused harm.

Precise Background Services provides a comprehensive suite of checks for employers, including national police checks, designed to surface the right information – lawfully, quickly, and accurately.

What Shows Up on a National Police Check?

A National Police Check (NPC) conducted through an accredited provider like PBS will typically disclose:

  • Unspent convictions across all Australian jurisdictions
  • Pending charges and findings of guilt where no conviction was recorded (depending on jurisdiction)
  • Spent convictions only where the role legally requires disclosure

It will not disclose spent convictions in circumstances where disclosure is not legally required – which is why understanding your sector’s obligations is so important before you order a check.

A Practical Guide for Employers

Do

  • Clearly define which roles require criminal history screening and why
  • Use an accredited provider to ensure checks are lawful and accurate
  • Apply a consistent, documented process for all candidates in the same role
  • Assess any disclosed convictions in context – relevance, recency, and role requirements all matter
  • Seek legal advice if you’re unsure whether a spent conviction exception applies to your sector

Don’t

  • Assume all convictions are automatically disqualifying – assess relevance to the role
  • Ask candidates to self-disclose without a formal, lawful process in place
  • Act on information obtained through informal channels (e.g. social media searches) without proper process
  • Overlook the importance of state-specific rules if your candidate was convicted interstate

Frequently Asked Questions

Does a spent conviction show up on a police check in Australia?
Generally, no. Spent convictions are not disclosed on a standard National Police Check unless you are applying for a role in a sector where disclosure is legally required, such as working with children, healthcare, or government positions.

Can an employer ask about spent convictions?
Only in specific circumstances defined by law. Outside of exempt sectors, employers are not permitted to ask candidates about spent convictions, and candidates have the legal right to non-disclosure. Breaching this can expose employers to legal liability.

How long until a conviction is spent in Australia?
For adult offenders, the standard waiting period is 10 years crime-free from the date of conviction or release. For juvenile offenders, it is generally 5 years. Serious offences are typically excluded from ever becoming spent. Rules vary slightly between states and territories.

What happens if an employee fails to disclose an unspent conviction?
If an employer has lawfully asked about criminal history and the employee or candidate deliberately withholds an unspent conviction, this constitutes grounds for termination or withdrawal of a job offer, regardless of how well-suited they are to the role.

Can I conduct a background check on all candidates?
Yes, provided you obtain the candidate’s written consent and use an accredited provider. PBS makes this process straightforward, fast, and fully compliant. You can learn more about our full suite of employer screening solutions at precisebackground.com.

Does PBS handle background checks for regulated sectors?
Yes. PBS provides tailored screening packages for healthcare, childcare, education, government, legal, and many other regulated industries across Australia – all designed to meet sector-specific compliance requirements.
