Known Corrosion on Qantas Jet in Feb 08?

This link leads to a discussion forum on airliners.net, a site much frequented people who work in the airline industry.

In a post made by user EK413 on the 25th of February 2008 he or she states that VH-OJK - the aircraft in this accident - was found to have “serious corrosion issues” whilst undergoing maintenance at Avalon airport. (Avalon is an airfield near Geelong in Victoria where Qantas have some of their aircraft maintained).
