While it is tempting to suggest Royal Melbourne West, the reality is that Mackenzie was not there when it was being built and the work there owes a great deal to his partner Alex Russell who was on site every day during construction, and to the curator/constructor Mick Morcom. Surely, in order to be his most representative course, one that he never saw during construction or once it was finished would have to be disqualified? To my mind Pasatiempo would perhaps best fit that bill.
