You will be doing well to get the Mac's or Monteiths seasonals in Oz as they don't normally ship the seasonals here.
As for the recipe it is a beauty.
I did stuff up a little and added the corriander seeds at the same time as the orange peel (at 15mins) where as the recipe I had called for it at 5mins.
The corriander didn't come through too much though which is good.
Hanging out to get home and have a couple tonight
If anything I would like to try the exact same recipe with the White Labs Saison yeast.
Beers,
