good morning!
we went on this trip last year, the last week of june. The weather was HOT!!! But dry heat, so it was quite nice, we are from Montréal so we're more used to hot muggy weather...The guides provided us with plenty of water and the bus is air conditioned.
Pack light clothing, I find that workout clothes are the best since the fabric absorbs heat (like Nike dryfit, just to name one). You don't need fancy clothing, even for the all adult night where you have dinner at Red Cliff lodge, kaki pants are more than fine.
Plenty of sunscreen, good walking shoes (or sandals) and a bathing suit...
You'll love this trip, we had a blast!!!
we are now counting the days....we're going down under on Dec 26th!!!!
