Melbourne entrepreneur Adrian Portelli, widely known through his luxury prize giveaway business LMCT+, has commenced defamation proceedings against former South Australian consumer affairs minister Andrea Michaels over comments she made concerning his company's operations in the state.

The case, which had its first hearing in the South Australian Supreme Court on Friday, centres on statements Michaels made after a South Australian woman won a multimillion-dollar property through an LMCT+ promotion but was later found to be ineligible to claim the prize under South Australian law.

LMCT+ operates as a membership-based rewards club, offering subscribers discounts and access to prize draws featuring high-value items such as luxury vehicles, cash and residential properties. The business gained national attention after Portelli purchased several homes featured on the television series The Block and incorporated them into promotional giveaways.

Under South Australia's gambling regulations, residents are subject to specific restrictions relating to trade promotion lotteries and prize competitions. Following the controversy involving the South Australian winner, Michaels publicly described the situation as "awful" and "terrible", expressing concern about the impact on the woman involved.

According to court documents, Portelli alleges that Michaels' comments conveyed defamatory meanings that damaged his personal and professional reputation.

The lawsuit specifically references statements reportedly made during media interviews and press conferences while Michaels was serving as Minister for Consumer and Business Affairs. Portelli contends the remarks suggested he knowingly engaged in unlawful conduct by accepting money from South Australian participants despite their inability to legally receive certain prizes.

Michaels had previously stated that Portelli had "created an awful situation" for the South Australian woman involved by permitting her to enter and ultimately win the competition despite regulatory limitations applying within the state.

The defamation proceedings emerge against the backdrop of broader legal scrutiny surrounding LMCT+'s business model.

Earlier this year, Xclusive Tech Pty Ltd, the company trading as LMCT+, was found guilty of conducting unlawful lotteries in South Australia and fined $40,000. However, Portelli himself was found not guilty of related charges brought against him personally.

Portelli has consistently defended the legitimacy of his business operations, maintaining that LMCT+ provides genuine products and services alongside promotional giveaways. He has also argued that differing regulations between Australian jurisdictions have contributed to confusion regarding compliance requirements.

The latest court action highlights the complex intersection between consumer protection laws, gambling regulations and reputational rights.

Defamation cases involving public figures often require courts to carefully assess whether statements constituted fair comment made in the public interest or whether they crossed the threshold into unlawfully damaging an individual's reputation.

At this stage, the Supreme Court has not considered the substantive merits of Portelli's claims. The initial hearing focused on procedural matters, and the case is expected to progress through the legal system in the coming months.

As the proceedings continue, both Portelli and Michaels will have an opportunity to present their respective arguments before the court.

The matter also serves as a reminder that high-profile disputes involving business regulation can extend beyond questions of legality and enter the realm of reputation, accountability and the limits of political commentary.

As with all civil litigation, the allegations made by the parties remain subject to judicial determination.
