Mr Portelli's company, LMCT+, describes itself as a "shopping tool and rewards club", offering shopping discounts for a monthly fee.
As part of the fee, members are also allegedly granted entry into monthly draws where cash and prizes can be won.
Advertising through social media, Mr Portelli claims to give away millions of dollars via giveaways that are then live-streamed.
Both Mr Portelli and his company, Xclusive Tech Pty Ltd, face a total of 19 charges of person conducting/assist in the conduct of an unlawful lottery.
Mr Portelli has been charged with nine offences and the company with 10.
The charges range in date from 29 January 2023 to May 16 this year, with Xclusive Tech charged over several lotteries that offered properties from The Block as a major prize.
As per South Australia's Lotteries Act 2019, any lottery that is not licensed in the state is unlawful, with organisers facing a maximum penalty of $10,000.
Mr Portelli is due to face court on 15 January next year.
