So - with my other hat on (Law Professor), I’ve just had a chapter published in this book. I don’t actually know how many people there are here who are interested in Australian contract law, but I thought I’d put it out there any way because - YOU NEVER KNOW. It does feature the rabbit-duck illusion (which I say applies to contract damages). https://www.federationpress.com.au/bookstore/book.asp?isbn=9781760022532
