MOS 121 4.08 refers.
Probably because that's what's specified in ICAO Annex 6 Part I - International Commercial Air Transport (Aeroplanes). The preamble of Annex 6 states, under 'Applicability':
Annex 6, Part I, contains Standards and Recommended Practices adopted by the International Civil Aviation Organization as the minimum Standards applicable to the operation of aeroplanes by operators authorized to conduct international commercial air transport operations.
CASA obviously adopted many of the Annex 6 requirements for domestic operations too; bastardised where necessary to suit our 'unique' operating environment
. I can only assume the dual runway requirement was not adopted for domestic use because the woeful lack of aviation infrastructure in this country made it all too hard.
