Put in a tape.

It is obvious from your signature that you probably have heads that
are polarized for the northern hemisphere instead of the southern
hemisphere where magnetic fields point the other way.  Short of going
to the electronics store to get what are usually callled "aussie heads,"
you might try operating your tape deck upside down.  You may also need
to adjust the tape speed to compensate for the coriolis effect which
is probably making your tapes run slightly faster than normal since
motors calibrated for the northern hemisphere have to turn the other
way.
