Copyright Aid

If I write a book in Australia (of which I am a resident and citizen), have it printed in China and privately launch and sell it mainly in the UK (of which I am a resident and citizen), where is it published and what copyright law applies to a) content which is the copyright of others? b) my content?

I wonder if the publishers address is the relevant factor but what if the address is an email address or website and not a physical address?

PS the composition, layout and press-ready files will be prepared in Australia.

Thanks, Andy. Can't believe its that sensible and simple.
