"Were they sold in Australia?"
Yes they were. Albeit only for a short while. Australian home laundries are not set up for gas or electric dryers that require a 20 amp outlet. If consumers want that, it costs lots of additional $$$. That is why here in Oz American full-size washer dryer pairs are primarily found in commercial operations, such as hairdressers, mining operations, caravan parks or residential settings like nursing homes.
Speed Queen and Maytag are primarily targeting commercial clients with their matching washer/dryer pairs. There probably wasn't enough demand for F&P's TL dryer to make it viable long-term here, unfortunately.
Unlike the US, in Australia appliance manufacturers never paired up with home building companies to furnish Australian houses with their products. Now we do not even have an appliance industry, only whatever stuff importers decide they want to sell here.
