We can disagree on that, but lets talk about Mr Joyce. He arrived in Australia in 1996 and joined Ansett, then worked for Qantas, becoming CEO in 2008.
He has performed very well for shareholders, finally bringing the airline back to significant profit in the last couple of years. This included bringing industrial action largely to a halt after the infamous grounding of the fleet, mostly not reducing fuel fines when the price of fuel reduced significantly, and by selling Qantas FF points by the A380-load to partners and making QFF members a product to be marketed to by those partners and making award redemption almost an Olympic sport, such is the difficulty in many situations.
All in all great for shareholders, but nearly all at the expense of Qantas passengers. He doesn't appear to have any Directorships outside of the Qantas group nor any charitable or philanthropic links that I can tell (eg his profile on Qantas web site and the inevitable Wikipedia article). His most prominent public advocacy, Marriage Equality is very much in his own personal interest.
In as much as CEOs of prominent companies inevitably get these gongs, he'll get one, but I can't see anything resembling 'service or contribution to Australia' other than running his airline in the best interests of its shareholders.
