No rule anywhere which states that a pilot with a licence may not do stalls but note the new definition of aerobatics. Don't abruptly pitch nose down to recover because that would be aerobatics!
A few years ago CASA redefined aerobatics as:
"
aerobatic manoeuvres, for an aircraft, means manoeuvres of the aircraft that involve
a) bank angles that are greater than 60°; or
(b) pitch angles that are greater than 45°, or are otherwise abnormal to the aircraft type; or
(c) abrupt changes of speed, direction, angle of bank or angle of pitch."
So no longer conforms to the ICAO definition.
