Transurban’s chairman-designate Craig Drummond says he will be across the “detail” when he succeeds Lindsay Maxsted in October as the toll road group takes a more conservative approach to cash management and project risk assessment.

“I’m very interested in the detail, I take nothing for granted,” Mr Drummond told The Australian Financial Review, adding he would have plenty of time to devote to Transurban given he does not chair any other big public companies.
