The man arrived in Sydney and was selected for a device examination by the Australian Border Force (ABF).

“On his phone, officers allegedly found over 100 images of CSAM, including anime and AI-generated pictures,” the ABF said in a statement.

“The man was detained for questioning then sent back to Malaysia. This also resulted in the cancellation of his visa.”

The Malaysian was among 17 travellers intercepted by the ABF in various parts of Australia including New South Wales, Western Australia, South Australia and Queensland between January 1 and 14.

Others allegedly caught with CSAM on their devices during the crackdown included Australian men aged 70, 57 and 24, and a 27-year-old Australian woman.
