Tony Walls, 57, is a Wollongong boy who went straight to work from Port Kembla High School, attended university at night and spent all his spare time programming computers.  He started his own business right before the early ‘90’s recession from a bedroom in his parent’s house. Objective Corp now employs over 400 people and Tony is one of Australia’s newest tech billionaires. Walls, a reluctant member of the Rich List, says leaders have to be careful not to believe their “own BS too much”; talks about why he races a McLaren 650s GT3 on weekends, and hasn’t sold a single share in his company in 20 years.
