Mason Staver, the son of prominent Melbourne real estate figure Arch Staver of agency Nelson Alexander, has reportedly entered an intensive rehabilitation programme costing around $5,000 a week after friends described his cocaine use as having spiralled "out of control". The case has drawn attention because of the family's prominence in Melbourne's property industry and the serious nature of the allegations involved, which reportedly include being caught with both drugs and firearms.

According to friends cited in the report, Staver's substance use escalated significantly before he was allegedly found in possession of drugs and guns, prompting concern from those close to him and his subsequent admission to a high-cost private rehabilitation facility. Specific details of any criminal charges, court proceedings or the exact circumstances of the alleged discovery were not fully outlined in the available material.
