Since May the all Ordinaries index of Australian stock prices has declined from 6000 to about 4400 which is a decline of about 25%. The value of the Australian dollar has over the same period fallen from about 0.98 US cents to a low today of just under 70 cents. This is a decline of a bit more than 25%. To be more precise one US dollar's worth of Australian equity four months ago in May was worth about 52 cents today.
Update: (Wednesday): The Aussie dollar collapsed to a bit over 64 cents last night. This is perplexing.
