Don't think Maytag exported to OZ, at least not wringer washers. More modern offerings are available (top loaders), but that's different.
Since everything works off the motor, a simple swap to a 240v/50hz seems all it would take to make an American Maytag wringer work for you. Shipping one to OZ likely would be an expensive and extensive undertaking should imagine.
Have seen Maytag top loaders pop up in UK and other parts of Europe, but those were machines bought by American military or diplomatic service that got left behind.
