Add to your piece....there was originally an understanding that the bulk of the work (90-percent) would be done in Australia, with Australians. Around 18 months ago, the French said there was a new understanding (probably around 60 percent of the work in Australia). That probably was the last straw, and the French government just weren’t wise enough to grasp that angle to the contract.
The French are notorious for changing deals after contracts are signed.
France did it to India after France won a contract for 36 Rafale fighters. All but the first few were to be constructed in India by HAL, but that part of the deal fell through and all 36 are being manufactured in France instead.
