SBS Radio MW frequencies.
This list might be helpful…lest you think you are receiving something more exotic! This applies to those outside Australia as well, for example a DXer on the west coast of North America who hears an Indian language programme- who might mistake SBS for a genuine signal from the subcontinent.
Canberra: 1440 kHz
Melbourne: 1224 kHz
Sydney: 1107 kHz
Newcastle: 1413 kHz
Wollongong: 1035 kHz, 1485 kHz
All the other SBS services are on the FM band, even those in the other capitals.
