Maybe McDonald is not quite so bulletproof in the pressure stakes. He admitted yesterday he was not enjoying his riding back this autumn and early winter. The juices were drying up just before he went on his annual two-month working holiday in Europe.
"I was unhappy because I wasn't meeting my own goals, so getting over to Europe came at the right time. I needed to get away and it has really helped me."
McDonald describes Australian racing at the top end as "a fishbowl".
"If you live in that environment, you get caught up in it. You have to from time to time get away from it."
He rode 19 winners in Europe, but the real pleasure came from the simple change of scenery.
The spark is back. "I haven't felt like this for a while. It is just good to be going to the races."
This is a game in which you never stop learning and McDonald says he is grateful for the experience in riding out mornings for trainers of class like Sir Michael Stoute and John Gosden. It taught him, he says, the importance of keeping your horse relaxed.
"Here in Australia you travel only a couple of hundred metres to the start, but in England it can be a mile away, so you have to keep your horses as relaxed as possible to avoid running your race before going into the barriers.
"It's an important lesson."
Watch the vision of Saturday's Golden Rose and you can almost hear the sigh of relief McDonald let go as he crossed the finish.
"I'm relaxed and fresh and back in a good frame of mind."
Yes, winning million dollar races can do that for you. But McDonald admits the Melbourne Cup is at the top of every jockeys' mountain.
