It seems that the Australian Standards Body still believes in corruption and money, and they will send Rick Jelliffe, an hardcore Microsoft representative who has been paid to edit the Wikipedia page on OOXML.
The Australian Standards Body seems to have taken this decision alone.
A nice comment that the Aussies should read:
Since you openly admit to being paid my Microsoft you immediately destroy any credibility as a neutral commentator. End of story.
Rick Jelliffe might be technically competent, but the credibility of the Australian delegation is put in jeopardy.
I would be from Australia (nice country, they have a little bit more sun then in Belgium), I would pick up the phone and call my Member of Parliament.
