Does anyone know where I can get cheap Kangaroo meat in Brisbane?

Does anyone know where I can get cheap Kangaroo meat in Brisbane for human consumption. Around $10.00 a kilo would be nice A lot of places have it but they want to sell it for 19.95 a kilo. I just cant understand why in this country its more expensive than beef when they don't have to farm it? Coles has it for around $14.00 per kilo but surly some butcher can do better then that?
