You can read the FWA decision yourself HERE or the order HERE from the Fair Work Australia website www.fwa.gov.au one thing you can read from the decision is point 10
 It is unlikely that the protected industrial action taken by the three unions, even taken together, is threatening to cause significant damage to the tourism and air transport industries. The response industrial action of which Qantas has given notice, if taken, threatens to cause significant damage to the tourism and air transport industries and indirectly to industry generally because of the effect on consumers of air passenger and cargo services. The Qantas evidence was that the cost to it alone is $20 million per day.Which to me is a slap in the face for Qantas as they are tarred with being detrimental and damaging to the countries economy.
There have been plenty of stories written and reported on through out the media but I recommend you read those published by Australian Business Traveller HERE and The Australian HERE
