Incorrect. All speed signalling aspects are available on an Automatic Signal in
Victoria.
It is very possible to get Medium speed aspects.

Red is used as one of the colors for Victorian speed signalling. In some areas, the
top aspect is a fixed red, showing only medium speed aspects on that signal.

Route knowledge should tell you when you are in a 3 position speed signalling area.
If the top light is extinguished, then you would assume the signal to be at the most
restrictive aspect ie: RED
the red light on the bottom tells you that there is a signal there and it is
defective.
