The boss of the Territory taxpayer-backed ambulance service draws a second income by renting a personal investment property to his own organisation. An investigation has revealed St John Ambulance NT rents a home from its CEO, Ross Coburn, in Darwin’s northern suburbs. Another senior St John staff member has also negotiated a similar arrangement, where they rent an investment property to their employer. St John refused to reveal how much it pays its staff in rent for the two houses, but rental data showed that Mr Coburn’s property in Tiwi was last publicly listed in 2008 for $450 per week. A spokeswoman for the organisation said St John arrangements were negotiated at arms-length on commercial terms and, despite being government funded, there was no obligation to tell the taxpayer where money was spent.
