Management consultancy firm Port Jackson Partners is proud of its alumni. Go to its website and you will find the smiling faces of several well known and high-achieving Australians. This includes ACCC chairman Rod Sims, former Fairfax CEO Fred Hilmer, and chairman of the Sydney Symphony Orchestra Terrey Arcus (Arcus and Hilmer founded the firm together).

And then there is Angus Taylor, the federal member for Hume and the nation's energy minister.

But Port Jackson appears to be less proud -- and is certainly less forthcoming -- about Taylor's legacy with the company, in particular its study into the economics of wind turbines.
