Yes, but the point is Australia has never needed to use the capability of the F-111. When we purchased it, it was purchased on the basis we needed a theoretical ability to drop an atomic bomb on Jakarta. We’ve never needed to, and that’s no longer a strategic consideration.
Describing the F-35 and the Super Hornets as a ‘replacement’ for the F-111 really gives a misleading impression. It just happens that the latest upgrade is coinciding with decommissioning of the F-111. Now it’s been decided what we need is primarily fighters (albeit with some ground attack capability) rather than needing any bombers.
The F-111C's long range, speed, and endurance were vital to your ability to intercept maritime targets in a timely manner. Air Power Australia has written many white papers (that I'm sure you've read) on the importance of the F-111 to the RAAF, and how inadequate either the F/A-18F or F-35A is at replacing that capability.
