Ansett had 2 divisions, domestic and international. They were separate entities and didn't interchange, like Qantas. However some aircraft were shared for both operations. Domestic crew operated 767, 737, 320 and 146 where as international crew operated the 747, 767 and 320. Only domestic crew operated domestic flight numbers and international crew operated international flight numbers, the only exception was Bali where it was operated on 767 and varied between both crews at times. The 747 was used primarily on Japan, Taipei, Korea, Kuala Lumpur and Hong Kong sectors, 767 to Shanghai, Jakarta and Bali, A320 to Fiji. Hope this answers your question.
