Millets currently have on their summer sale, with up to 50% off lots of different ranges. So there is no better time to grab yourself a bargain. Anyone planning a trip to Australia should definitely invest in a good quality rucksack, and there are some very good models in the sale, starting from around £35 upwards. I would also advise you invest in a good pair of hiking boots if you don't already have them, and again there are some great styles in the sale.
