Aussies will get their backdoors to services operated by Aussie companies. What happens outside that could be popcorn-time.
In an ironic twist, it was an aussie (Eric Young) who first gave us SSLeay, the ancestor of OpenSSL, back in an era when Oz was part of the Free World and the US was almost-uniquely restricted.
I wonder how you could modify OpenSSL to open a backdoor for malicious third-party-key injection? No, I'm not going to work on it.
 Among developed countries.
