Hi & welcome to MR. Probably not the wisest choice to publish your email addy - so you might want to take it out.
Have you tried
The National Library of Australia - not sure if there is sign up fee though.
You didn't say where in Australia you are, but here in Brisbane the library does have an eBook section. So try googling the libraries in your area.
For a good resource of great edited eBooks for free try the
subforum here. All books were created by MR members, mainly from the Gutenberg project.
There are heaps more good tips here on MR where to get books from too - a lot of authors are here and offer books at low prices or even free. Keep an eye out on the
Freebie subforum.
I hope this gives you a start. If you still need more info, keep looking and if in doubt, asking.
