Uh oh, I've made an arse of myself by not watching the video first 😆
To apologise, I've taken the time to look into the actual person/account you were talking about 😆 'The Last Place On Earth' have a website (looks to run on Substack) and a podcast.
There's also a text article about that particular encounter (https://www.lastplaceonearth.com.au/running-polling) that was co-published with Crikey, at which point I think it's totally fair to just call them a journalist.
