So, in your shoes, I'd probably write letter that said something to the effect of, "Dear editor, I am writing to follow up your recent conversation at Venue, with my uncle, Favorite Person. As he mentioned, I have recently had a novel accepted by a small press in Australia to be released at the end of 2019. [brief reminder of novel's details.] You were kind enough to suggest to him that I get in touch with you directly.

You will probably not be surprised to hear that I am about to begin the query process for my next novel. [query pitch].

Thank you so much for giving me this opportunity. Any advice, any information, any suggestions about agents, any feedback on the enclosed pages, or about pitching my work to a prestigious publisher like [name of editor's publisher] would be gratefully received."
Something just like that sounds great. Let everyone know how it goes! and Good Luck
