This is true. However, AM stereo never really took off in Australia, other than for car radios, although a number of stations either did or still do use it. I don't actually own an AM stereo receiver.
These days in Australia, most of the music stations are on FM while the AM band is mainly for talk stations. In the capital cities where digital radio exists, all the major AM and FM stations simulcast in digital stereo, along with other digital only stations.
