You may require a national police certificate as part of the application process for a licence, registration or other approval. Some employers or volunteer organisations may also require you to provide a national police certificate prior to commencing employment or volunteer work.
A national police certificate is a full record of your criminal history. It displays all criminal history records (sentences, convictions and findings of guilt) held against your name by police services across Australia. In some cases, you may also be required to undergo a fingerprint search.
