You guys have got to be kidding right?
QF advised the VA crew of their intention to do an approach and stated that they had fuel issues. They then ask VA what their intentions were.
VA after attempting a DME arrival for visual approach decide to allow QF a go.
QF don't know the state of VA's fuel. VA don't communicate anything about their fuel.
QF are also committed to Mildura. So they manage their situation.
VA manage theirs.
WHAT IS THE PROBLEM?
Get over it!
