I agree it is lovely, although fairly isolated, especially as it is so far up the top of Qld. But you wouldn't really need to go anywhere else for shopping or anything.
LOL, you think Mackay is in Far North Qld?! I think Mackay only touches the south border of North Qld. It's about 8hours south of Cairns.
It is hot and humid, but not as bad as Townsville or Cairns. So providing you like the heat, you'll be right

ETA: I think Tali is in Mackay now, isn't she?? Maybe she'll pop in.
