A 43-year-old Malaysian has been deported from Australia this morning after his mobile phone was found to have contained videos of "extreme sexual depravity and violence", Australian authorities have said.

The Australian Border Force (ABF) stated that the man, whom it did not name, was detained upon arrival at Perth International Airport on Wednesday after an inspection of his phone revealed the videos.

The man, it said, had arrived from Malaysia with a tourist visa and had been stopped for a baggage examination.

The ABF is an independent operations body underneath the country's Home Affairs portfolio tasked with, among others, customs services, as well as investigating and enforcing immigration infractions.

"A 43-year-old Malaysian man who arrived at Perth International Airport on July 11, 2018, has been removed from Australia after abhorrent material was located in his mobile phone.

"During examination of the man’s phone, ABF officers discovered a number of videos depicting extreme sexual depravity and violence deemed to contravene the standards of morality, decency and propriety under the Customs Prohibited Import Regulations.

"Officers seized the phone and subsequently cancelled his visa," the ABF said in a statement issued today.

It went on to state that the man was detained and transferred to the Perth Immigration Detention Centre until his subsequent removal from Australia earlier this morning.

Its Western Australia acting regional commander Mark Wilson said: “Visitors to Australia need to be aware that we are constantly on the lookout for this sort of prohibited material, in addition to the terrible imagery involving child exploitation we are continuing to locate.

“Videos depicting extreme sexual deviancy and acts of horrific violence are not acceptable in our community and anyone caught engaging in this behaviour risks forfeiting their right to be here.”

The ABF, however, did not state if the man had been charged for the possession of the said prohibited material and if Malaysian authorities had been notified prior to his deportation.
