On the other hand, a Google search for "sast time zone" shows nothing
but South Africa, and "sast time zone australia" still shows South
Africa except for the first result.

And a grep for SAST in the source tree shows:

src/timezone/tznames/Australia.txt:SAST 34200 # South Australian
Standard Time (not in zic)
src/timezone/tznames/Africa.txt:SAST 7200 # South Africa Standard
Time
src/timezone/tznames/Default:SAST 34200 # South Australian
Standard Time (not in zic)

I'm not sure exactly what that means but it would make sense to me that
the default should be the one not marked "not in zic".
