I noticed on the old Tek forums there were many inquiries from newcomers to Linux asking about how to get started on this system or how to solve basic problems that arose.
One of a few Youtube channels that helped me was the ‘teklek411’ channel on Youtube (and yes, he is an Aussie lol)
*I’ll state outright that I have no affiliation with ‘teklek411’ in any commercial-sense.
Teklek411 provides some basic Linux video-tutorials to assist beginners to make the transition to Linux, namely Ubuntu (and this can only be a good thing in the short to long-term)
