I don't what you consider humid? Brisbane gets very humid during the summer months. Queenslanders tend to say it's too hot for 6 weeks, too cold for 6 weeks and perfect the rest.
P.S
Try telling anyone in Brisbane right now it's not humid!
Hi, When I was in Brissie vodafone had the best deals on pay as you go. Also get your sim from coles or woolies as they only charge a dollar or two where as the vodafone shop charged us $20 each!!
good luck
