He was charged with more than 30 deception offences after being investigated by Consumer Affairs Victoria, and an arrest warrant was issued after he left Australia, according to Fairfax Media
Leong is the former director of the training company Keat Enterprises which went into voluntary liquidation in June 2014.
The company was found to be posting fake job ads on employment websites, and then convincing interviewees to buy expensive in-house training.
Last year, the company was convicted and fined $165,000 for more than 30 breaches of the Australian Consumer Law (Victoria)
, including engaging in conduct likely to mislead job seekers and accounting graduates into enrolling in its courses.
This included posting 23 online ads for internships or employment between February 2013 and May 2014. In reality, the company was using the ads as a means of attracting people to enrol in its training courses.
After applying for the jobs, people were invited to attend an ‘interview’, where they were marketed, offered or sold training courses, typically priced from $2000 - $3000.
This was despite the ads claiming that Keat Enterprises was offering part time or full-time employment and salaries that ranged from $30,000 - $50,000.
In fact, the ads did not mention any costs would be paid by the job seeker.
According to a spokeswoman for Consumer Affairs Victoria, Leong is facing 23 counts of engaging in misleading conduct as to employment, and 10 counts of making false and misleading representations as to the supply of services.
Leong was also the director of a waterproof T-shirt company, a modelling agency and a superfoods lab.
