When Australia post their currency, it states A$ or AUD.
Australia it is almost always abbreviated with the dollar sign ($); A$ or AU$ are often used informally to distinguish it from other dollar-denominated currencies.
Usually you see the Canadian $ as CAD. The Canadian dollar (sign: $; code: CAD) is normally abbreviated with the dollar sign $, or C$ to distinguish it from other dollar-denominated currencies.
With multiple markets involved, one would think that they would distinguish this on the share tender form.
Gook luck to those that are riding this out!!!
