After 10k I had to navigate a big hill with limited views from the top. A bit tough carrying 8 liters of water as there would be none before I reached the coast 100k later. It that sense Australia is a third world country - every place except bigger towns have to accept living without clean drinking water except rainwater. How it's not possible to get clean groundwater in hilly/foresty regions is a puzzle to me - maybe it's a question of money as everything here in Australia.
