This is where things get serious. Water. You can’t survive without it, and in much of South Australia, finding it is a challenge. How much water are you carrying? A couple of stubbies isn’t going to cut it. Invest in large water containers, like sturdy jerry cans or collapsible bladders. And what about purification? Even if you find a water source, is it safe to drink? A good quality water filter or purification tablets are essential. Don’t underestimate the importance of this. Dehydration can sneak up on you fast, and a busted water system is a one-way ticket to trouble.
