In 2005, Mr Green founded GCG Health, Safety and Hygiene, an occupational health, hygiene and safety services provider that deals predominantly with the mining industry. Starting as a 25-year-old sole trader, Mr Green has grown the business into a 42-person operation with four offices and a nationwide presence and clients that include BHP, FMG, Rio Tinto and Xstrata. With their understanding of workplace safety, GCG continues to sponsor Police Blue Light, a program that produces safety booklets for school leavers, outlining the dangers of drugs and alcohol as they embark on their lives away from the security of school life.
