Interestingly, someone on the Jubilee Ave had already seen these pictures and asked the club who confirmed the Illawarra jersey WILL remain as the alternate for 2013.
So perhaps these diagrams were concepts that were yet to be ratified by the club?
I'm quite confident the CS jersey is correct (the club said we were having a new design in 2013, and Reebok have had a fascination with making our merch black - see 2009 charity shield jersey for comparison below) and I think if Reebok designed that heritage it was at the request of the club, so it makes sense.
Perhaps the blood and bandages is for ANZAC, perhaps it was Reebok's away jersey suggestion that got knocked back?
