This chart shows information from the Internal Tax Office documents that reveal a case against a trucking company owner and Hells Angels associate from Adelaide, accused of defrauding the Commonwealth of $5 million. The alleged fraud involves false claims by bikies for Commonwealth rebates on diesel for fictitious trucks. The scheme is said to be orchestrated by an accounting firm in regional Victoria, owned by Melbourne Hells Angels' strongman Peter John "Skitzo" Hewat. Tax investigators suspect a national network exploiting federal government subsidies in the trucking industry. The fraud involves fake identities, paper companies, and false claims for diesel rebates. The bikie allegedly controlled a post office, allowing the use of PO boxes under false identities. The Tax Office links the Adelaide Hells Angels associate to the Victorian Hells Angels and Hewat through the accounting firm, which served as a mailing address for companies tied to the alleged fraud. While a criminal investigation against the trucking industry identity has stalled, a civil case is ongoing. The Tax Office has connected him to Hewat and the Victorian Hells Angels, linking the accounting firm to 50 other trucking companies suspected of fraudulent rebate claims. The alleged fraud involves schemes related to diesel and alternative fuel grants and fuel tax credits.
