OK.
It is called the Centre Tank. If it had a leak then perhaps they could have not used the Centre Tank and planned a tech stop short of SYD using only wing fuel. (Engines are fed from the Inners on the A330).
I guess all will be revealed. Perhaps it wasn't a "leak"
Arriving without the necessary certification? Are you suggesting EWL that they departed SYD without the Return to Service having been signed? Or without an MR? Oh dear.
