Marine Olympus powered a lot of ships.

Many Olympus engines are still in use as peak demand power generators in static installations.

Not that odd.  Olympus was a very successful power plant in industrial power generation and marine applications.  It was pretty much the standard turbine for the Royal Navy: Bristol, Invincibles, Type 21, Type 42, Type 22.  It was widely exported as well.

Do you guys know the armament of any other data of this Vickers modified Invincible? (Dimensions, aircraft complement etc)
The little drawing shows a single Goalkeeper CIWS forward of the Bridge and what looks like a SAM aft which can be lowered down under the flight deck in case of aircraft operations.

The modified Australian had two CIWS but there was no SAM armament.

I see!
Thank you!
Ahh that is the letter M (or W? ) on the aft and not a "pop-up" missile launcher I first thought of!
Could this proposal a variation of this other Vickers Light carrier design from around 1982?

Yes, that's the carrier deck letter code M (for Melbourne).  The British Invincible-class carriers had the deck letter codes N (Invincible), L (Illustrious) and R (Ark Royal).  Sort of a last check to make sure you're landing on the correct carrier.

Had a chance to think about this part of your post.

No, the Australian Invincible proposal was not related to the Vickers Light Fleet Carrier design at your links.  The RAN Invincible was a relatively modest modification of the original RN Invincible (reduced armament, expanded hangar space). The Light Fleet Carrier was basically a clean sheet design intended to be much cheaper than the Invincible. 

The Vickers light fleet offering had a new hull shape based on a passenger liner, commercial design practices with a few military modifications, and other cost savings throughout.  Notice the difference in engine exhausts, for example.  Invincible had two widely-separated stacks, reflecting two well-separated main propulsion machinery spaces with four turbines.  The Vickers Light Fleet has only two turbnes (and about half the horsepower) and only one stack, suggesting that there is one machinery space or perhaps two without much separation.

I will intend to draw this modified Invincible for the Australians in the near future and I would like to aks to what kind of Sensor suite should I put on her?
The same as the Invincibles?
Some newer radars?
Mixed British and maerican?
If yes what types?

I also wonder if the Shah of Iran before the 1979 revolution would buy the original Invincible design (if I remember he too wanted 3-4 such ships) or this modified proposal?

There are certainly such claims, but it's not clear how serious the Shah's enthusiasm was, and what exactly he wanted. In a lot of respects, he seems to have treated defence exhibitions the same way a child treats a sweet shop.

Bingo. You nailed it well, and I share your opinion. Before buying Tomcats, the Shah got a proposal from Lockheed to turn the mothballed fleet of A-12 Oxcart into YF-12s. I suppose Lockheed reasonned in the same way as you.

I have a question or rather two:
1. Does anybody have a high quality high resolution drawing of the Invincible class?

2. More importantly what is the accurate dimensions of the Invinvible class?
I've found two set of data regarding this in various books and sites:
A: 192,6m pp, 206m (206,3) oa length x 35m beam flight deck (27,5 wl)
B: 193m wl, 210m oa length x 36m beam flight deck (27,5 wl)

As I'm started to draw this modified Invincible accurate data on the original would be quite helpful!
