Absolutely not. Until the deal is given "interim approval to begin commercial planning" by the ACCC QF and EK officials are not even able to meet/talk to begin building the agreed tie-up, let alone do things like you suggest.

I also would be interested to know (under relevant data protection laws etc) whether they can legally even hand over your emails to another company, and I would also question the commercial sense of them doing so - why would QF give its customers data to another company when they could just directly email you any such deals (that would emanate from the new partnership) themselves?

I would thus strongly suspect that EK got your email address some other way.
