Just shows you that in an A330 OOL-BNE having heaps of fuel wouldn't have gone astray......I'd say 30 tonnes to start ( obviously considering MLW at BNE and RTOW at OOL) That should give you heaps of holding. Nothing more embarrassing than having to divert for the second time when you could have easily loaded the gas. Cause when things turn pear shaped........
I guess 20/20 hindsight is a wonderful thing now though...
