This is the fourth and last part of my Royal Australian Navy Never Were designs with drawings. Here I post the modified Invincible design offered for the RAN

 

Vickers Modified Invincible for Australia:

Similar to Canada, Australia too modernised it's navy with American made equipment in the late 1960's and early 1970, replacing its de Havilland Sea Venom fighters with McDonnell Douglas A-4G Skyhawks and their Fairey Gannets with Grumman S-2G Trackers. During this time HMAS Sydney was not modernised, but provided an excellent platform as an LPH during the Vietnam War, while the replacement of Melbourne became a major political issue at the time. Since the mid 1970's the Navy looked at various proposals including a modified Invincible from Vickers of the Royal Navy, the Sea Control Ship design and the Iwo Jima Class of the USN and the Italian Giuseppe Garibaldi class of the Italian Navy, though probably more shipyards offered similar designs like the Spanish SECN (Sociedad Española de Construcción Naval) or the German Blohm + Voss shipyard's various MEKO designs. Eventually the Invincible design was discarded as it proved too expensive to build and the Iwo Jima class was preferred due to it's capability to easily modify to handle VSTOL aircraft and command facilities.
I draw the Vicker's proposal, which as the sketch drawing shows would be very similar to the original Invincible though the most prominent changes were:
a thinner superstructure,
no GWS.30 Sea Dart missile launcher,
slightly longer and larger flight deck and
enlarged Hanger area to hold more aircrafts and helicopters.
 
A few years later just before the outbreak of the Falklands Conflict the Royal Navy sought to reduce it's carrier force to only two ships and offered Invincible for sale to Australia, which they seriously considered and eventually accepted. The Australians considered removing the GWS.30 Sea Dart launcher as to not only create more deck space but because Australia already using the USN's Standard SAM system, maintaining two separate systems could not be affordable to them. These modifications might had result to the Invincible to look like as she was been in the early 2000's after her 2nd refit.
But as the Falklands Conflict escalated the Royal Navy needed all her carriers resulting in Invincible sailed to the war zone and became the longest sailing on sea aircraft carrier of the Royal Navy on sea . After the war the Australian Government offered to release the UK from the sales contract if it wished. The offer was accepted, Invincible was retained by the RN and Melbourne was withdrawn from service in 1982 without replacement.
 
In both cases, either the newly built Invincible design or HMS Invincible herself to be renamed in Australian service as HMAS Melbourne
 
The design the following characteristics: (Same as the Invincible as built)

Speed: 52km/h (28knots)
