Australia have taken their complaints about the scheduling of the men's hockey at London 2012 to the International Olympic Committee.
Kookaburras coach Ric Charlesworth was furious his side will have to play three of their five pool matches at 8.30am, meaning the players' day will begin more than three hours prior to that start time.
The Australian Olympic Committee's director of sport, Fiona de Jong, has made their views known to the IOC.
"The IOC responded to me saying it was a hockey matter, but that the IOC was definitely involved in this initial schedule and so they would be involved in the reconsideration by hockey," she told The Age.
"They know that we mean business and that on these matters we will go down swinging and do everything we can to pursue a result that we think is fair and equitable."
