[5][7] On 8 May 2004, in a match against the Waratahs, Hynes scored the first ever Reds try at Suncorp Stadium in front of a record Australian Super 12 crowd.
It was the middle of several lean years for the Queensland team and the backline players being starved of possession under a 10-man rugby gameplan was frustrating for Hynes.
[9] In November 2006, Hynes played for the Australian Prime Minister's XV against Japan in Tokyo, scoring the opening try in a 61-19 thrashing of the home side.
[9] In the second Test against France on 5 July 2008, Hynes scored his first try for the Wallabies in front of his home crowd at Suncorp Stadium in Brisbane.
[8] He never shook off lingering knee problems, even after a mid-season arthroscopic operation,[13] He nevertheless returned to play for the Wallabies with a win against Italy in Melbourne on 20 July 2009.
[15] After many months of treatment in 2011, Hynes decided to undergo a radical surgery to guarantee he wouldn't experience severe pain or have any limitations in his knee later in life.
The innovative surgery involved a posterior cruciate ligament reconstruction; a high tibia Osteotomy, whereby his leg was broken and re-aligned; and a donor meniscus transfer.
