Hi, this question is quite tricky.. According to my knowledge, Mifold have 3 versions. US for the United States, Canada version for Canada and EU for European, and Asia. It specifically states that it is not meant for Australia. So it seems that all the 3 versions are not tested to be used in Australia. You might want to ask Mifold company directly for their official suggestions if you want to use it for Australia?
I am sorry that there is no favorable answer today. Feel free to let me know if you need anything else.
