That’ll be Franco. I think he’s in QLD and is Henry’s distributor here. The youtube stuff you find on them are usually made by him, and he’s active on the bushwalk forum. Buying through the Tarptent website is the only way to buy them officially, and you have to pay postage, but it’s usually already been sent to Australia and is waiting at Franco’s place for you to buy it.
