FGD135, the most remote capital city on earth is Perth and it is not covered by any remote airport policy although Qantas now has a AV for Perth. I agree there is no black and white with TTFs and I refer back to my original statement that CASA won't provide an opinion until you are involved in an incident that is related to the weather forecast then it will be the pilot's fault. Whenever I go to Perth, Darwin, Cairns or Townsville I always have an alternate regardless of the forecast.
