Anybody know what mint this pendant sized bar may have come from?

The mint mark is pretty clearly visible in the middle of this tiny bar. To me it looks as though there is a very small picture of Australia to the left of the "S" shape..

Does anyone happen to know who this logo would have belonged to? The bar itself is very old so I wouldn't be surprised if the maker is no longer around these days.

Thanks in advance

I may be wrong. Just a wild guessing.

Very close but I don't think so. I'm at a loss as to who this logo belongs to and what mint may have produced this bar.
