First of all, if you want to debate facts, perhaps you should try using them? Here is EXACTLY what the chief of Australia's F-35 acquisition program said:
So where does the 'increase' to $24B even get mentioned there?
Secondly, you need to understand these are package costs, not per unit costs. The 'package' includes infrastructure upgrades, training and support systems, weapons and everything you need to operate these aircraft as a capability and is therefore ALWAYS larger than just the cost of an aircraft.
Some nations, Australia included, includes costs such as fuel, the cost of aircrew (even down to salaries...) and other actual expenses, some do not. The 'surprise' cost of the Super Hornets, included EVERYTHING you need to operate 24 Super Hornets at their planned flying rates for an initial 13 years of service. JSF is similar.
So tell me, does every aircraft program include all these costs in their public statements? The answer is a simple no. So don't bother trying to 'compare' costs because they simply aren't comparable unless you are aware of all the factors that go into those costs.
As an example:
The publicly stated value of Saudi Arabia's 72x Eurofighter purchase is £20.9 Billion. (AUD $42.9 BILLION) at present.
The publicly stated value of Australia's 72x F-35A purchase is AUD $17 Billion.
(Time to impersonate typical internet Anti-JSF'er).
HOMG! That means Eurofighters cost AUD $595m EACH right???
No wonder we are buying F-35's! They only cost AUD $236m each!
You do understand what the term 'development' means don't you? Problems are found in testing. They are studied, fixes identified and tested again and resolved.
F-35 is in DEVELOPMENT. It is not yet finished. Why is it an issue when a minor problem with F-35 is identified, the internet screams blue murder? When a PAK-FA crashes, there is no apparent problem?
Remember the engine fire 'problem'? Problem was studied, the cause was identified and a solution devised and rolled out to the fleet.
Remember the catapault problem? The internet proclaimed the death of the -C model over that 'unsolvable design issue'. Except a professional engineering and test effort easily solved that 'problem' without issue...

Remember the 'melting decks and exploding asphault' 'issue'? The internet proclaimed the 'death spiral' for the - B model over that 'unsolvable' issue. Well call me crazy but it appears they managed to solve these 'problems' too...
