No! I don't! (to quote a line from Blackadder)
But that has always to me been the sensible option: Warriors have to travel x hundred miles over a fortnight, may as well stay in Australia for the mid-week period and save on money, get the team used to heat/time etc.
And if there's a playground available, well, why not?
Heat? I can assure you there's no heat in Canberra it's bloody freezing here! Was in Auckland last week and it's much warmer there.
