I bought a sixpack of coopers Pale (in Brisabane) last summer and tried to culture the yeast, but didn't get any action from it whatsoever.
On closer inspection the yeast appeared to be quite dark, almost brown in colour, not pale cream or off-white like rehydrated dry yeast.

I bought another pack ...

Whatever you do, DON'T boil it !!. I did that once, and ruined a batch of what probably would have been a good stout. ( I did the same recipe again and only steeped the grains in hot water - it was OK)
