Gordon, I am on Sky Muster & have no problem accessing my Foxtel account or the online guide.
My guess is your browser or PC is displaying the incorrect country or you have your location blocked.
have you tried different browser, like FF or Chrome?
If that is not the case; talk to your ISP, HarbourSat i think it is from memory, as they may be of more help than level 1 Foxtel staff. I doubt it's Foxtels problem.
EDIT: To turn on or off the location of your PC.
