I have written a children’s book. I don’t quite know how to go about getting it published ... I can’t seem to find the finances to even get it illustrated ... could you perhaps offer me some advice?
Yes: call the Australian Society of Authors or join the writers centre in your state; send submissions to agents; check the websites of publishers who publish picture books and see if they're taking submissions. And before all of that, make sure that your manuscript is as good as it can be - children's picture books are pretty much the hardest type of book to get published for a new writer (for the reasons giving here).
