Do publishers pick up self-published books?

Some publishers will look at self-published titles, especially if the sales are solid and readers keep asking for more. Australian book publishers might also check how the author is reaching people, how big the audience could be, and what has happened so far with earlier work. When I look at it as a student, I see self-publishing as one way to show you can deliver a book, before you go to a traditional publisher.https://www.australianpublishers.com.au/poetry-poem-publishing
