Roger you are correct, my apologies. I checked out the ATSB report and they said this:
"The flight crew jettisoned some fuel to reduce the overall landing weight to 445 tonnes, which was above the maximum landing weight of 391 tonnes. The flight crew then
prepared to conduct an overweight landing."
So the journalist was sensationalizing somewhat. It was not above the maximum landing weight as they did an "overweight landing."
