A Sydney man who allegedly sent more than 17 million fraudulent text messages in just one week is facing a “highly complex” court case.

Xuan Su, 39, was arrested on December 12 at a Moorebank home, in Sydney’s southwest, after cybercrime detectives seized SIM cards and electronics in their investigation into an alleged SMS phishing scam.

During a search of the home, police found two active SIM boxes, SIM cards and electronics that detectives allege were consistent with running the fraudulent scam.

SIM boxes hold more than 250 active SIM cards and have the ability to send up to 150,000 messages a day.

Mr Su is alleged to have sent more than 17 million messages, pretending to be from companies such as Australia Post and Linkt.

He has been charged with using equipment connected to a network to commit a serious offence and dealing with identification information.

The latter carries a maximum sentence of 10 years in prison if he is convicted.

Mr Su on Wednesday appeared at Campbelltown Local Court where a prosecutor from the Commonwealth told the court that a brief had been partially served on Friday.

“The matter is highly complex, there is a large volume of evidence,” she said.

Mr Su listened from the back of the courtroom as his matter was adjourned to July to allow his lawyers to be served the full brief of evidence against him.

The State Crime Command’s cybercrime squad established Strike Force Kanbi to investigate the use of SIM boxes after bulk text messages were found allegedly containing fraudulent links.

Court documents allege Mr Su dealt with Australian drivers licences, passports and personal identification information with the intention of committing fraud between September 2022 and December 2023.

He is also accused of connecting equipment to mobile devices with associated subscriber identity module cards.

Mr Su will return to court in July.
