I will admit 207 minutes ETOPS which is currently the limit on the 777-300ER may be a problem. 240 minutes is pending though and as can be seen it isn’t a problem from Perth and only requires a slight diversion North to remain inside 240 minutes of a suitable alternate from Melbourne.
Airports used to support ETOPS:
