G'day Rtswa,
I am not sure but I beleive the canada dollar compared to the Australian dollar is the difference in your number. Yesterday Blr traded at .3. Today someone offer .6. Whomever was selling recently must look a bit out of sorts.
To answer your question, I read that it is not .618 but is .6. But I stand to be corrected.
Good luck.
