A Brisbane man has been fined $2 million for breaching the Spam Act in an elaborate SMS messaging scheme involving dating websites.

The Federal Court in Brisbane found Scott Gregory Phillips was the mastermind of a company that sent unsolicited text messages to lonely hearts who had signed up to internet dating sites.

Their mobile phone numbers were gathered by company employees who had set up fake profiles.

The victims were then charged up to $5 per text message.

Justice John Logan told the court the scheme involved "systematic and studied deception" of those who used internet dating websites.

He gave Phillips 28 days to pay the fine.

Phillips was also banned from setting up dating or social networking profiles for seven years apart from personal use.
