The AFP said in a statement that the man, from Killara in NSW, had abused his position to use the processing power of the computer network at his place of work.
It claimed that he had earned more than $9000 through this act. The man was due to face court on Tuesday and could face up to 12 years behind bars.
The AFP said it had searched his house on 5 March and seized a laptop, phone, identity documents and data files.
“Australian taxpayers put their trust in public officials to perform vital roles for our community with the utmost integrity," he said.
"Any alleged criminal conduct which betrays this trust for personal gain will be investigated and prosecuted.”
The man has been charged with two offences:
- Unauthorised modification of data to cause impairment, contrary to section 477.2 of the Criminal Code Act 1995 (Cth)
- Unauthorised modification of restricted data, contrary to section 478.1 of the Criminal Code Act 1995 (Cth).
The first offence carries a maximum term of 10 years, and the second two.
