That list claims the Australian Working Holiday Visa is (quoted from article: "designed to allow digital nomads to spend a year in the country with the ability to apply for an extension". It's definitely not designed for digital nomads, it's designed for backpackers doing short stints of casual work, especially in fields like agriculture, mining, and construction [1]. Hell, to get the extension you need to work for 3 months in the above fields. And getting it that wrong puts the rest of the list into doubt.
