Sir Ivan Holyman also wanted to expand ANA's activities to cover international routes, but this was largely prevented by the Commonwealth Government holding an effective monopoly on Australian-based international air travel through its own airline QANTAS. ANA aircraft occasionally flew overseas under contract to the Commonwealth Government (such as immigrant flights between Australia and Italy in the late 1940s). ANA also commenced regular flights to North America in 1947 using DC4s, main stops being Fiji, Honolulu, San Francisco and Vancouver, not including refueling stops over the Pacific. ANA also had overseas commercial aviation interests through shareholdings in Cathay Pacific and Air Ceylon.
