My understanding from his various posts online (and website [1]) is that he owns and lives near the land where the filming takes place. In Far North Queensland these sorts of areas would not be difficult to come across, not even far from a major town.
He probably just walks or (more likely) drives home each day.
"Also It should be noted that I don’t live in the wild but just practice this as a hobby. I live in a modern house and eat modern food. I just like to see how people in ancient times built and made things."
Insect-wise, Ross River Virus is a problem in that part of the country. It's spread by mosquito. You wouldn't catch me outside at night up there in summer, at least not without protection.
