The last white paper provided the sea lift numbers, having been rethought since the East Timor operations. A few decades ago the RAN operated Sydney and Melbourne carriers. The Melbourne wasn't replaced, the Sydney was by a much much smaller Tobruk. Its my opinion the RAN missed the Sydney more than the Melbourne during East Timor. Without our allies sea lift help, the ADF wouldn't have been able to pull off the operations in East Timor.
And if Australia cannot do landing operations self sufficiently in East Timor, it does leaves one to wonder whether Australia could sea lift the army to defend Tasmania....
Since East Timor, Australia has been increasing its sea lift and air lift elements of its defence forces. And for very good sound reasons. I wonder why?
There is a reason why Australia bought 4 C-17s. There is a reason why Australia is buying 3 amphibious ships, 2 of them large. To reach Australia's new minimum sea lift and air lift numbers stated by policy......
Australia was increasing it's lift way before Timor ever came onto the horizon, it just went about it in an absolute "dogs breakfast" way.
The Newport LST's that were acquired by the RAN in the mid 90's were meant to provide the amphibious lift that was eventually required for Timor, except we stupidly went and bought "cheap" appearing but in reality absolutely shagged rust-buckets.
What was meant to be a cheap way of increasing our amphibious capability turned into an expensive one when one bad decision was followed up by another - spending hundreds of millions to re-condition and modify these ships into the HMAS Manoora and Kanimbla vessels we have now. The $500m project to acquire brand new ships was deemed too expensive, but $470m on second-hand rustbuckets was perfectly fine (nice work Mr Keating. Almost as useful as your F-111G purchase)...
Obviously they have turned out okay and provide an adequate level of capability, but it was a torturous and expensive way of doing things that was most un-necessary.
Kanimbla and Manoora were eventually fitted out, refurbished and brought into service, they just couldn't do it in time for Timor, hence the need for HMAS Jervis Bay...
