Early years

Born on his mother's birthday[1] to Lyn and Bob Irwin in Essendon, a suburb of Melbourne, Victoria, Irwin moved with his parents as a child to Queensland in 1970. Irwin described his father as a wildlife expert interested in herpetology whilst his mother Lyn was a wildlife rehabilitator. After moving to Queensland, Bob and Lyn Irwin started the small Queensland Reptile and Fauna Park, where Steve grew up around crocodiles and other reptiles.
Irwin became involved with the park in a number of ways, including taking part in daily animal feeding, as well as care and maintenance activities. On his sixth birthday he was given a 12-foot scrub python. He began handling crocodiles at the age of nine after his father had educated him on reptiles from an early age. Also at age nine he wrestled his first crocodile, again under his father's supervision. He graduated from Caloundra State High School in 1979. He soon moved to Northern Queensland, where he became a crocodile trapper, removing crocodiles from populated areas where they were considered a danger. He performed the service for free with the quid pro quo that he be allowed to keep them for the park. Irwin followed in his father's footsteps, becoming a volunteer for the Queensland Government's East Coast Crocodile Management program.
