Using the 777 on domestic ops is allowed, it's just not cost efficient or sensible. The cost per seat/kilometre is WAY higher than a 738 and the facilities with regard to aerobridges and gate lounges is sorely lacking at most domestic ports in Australia. The Nadi flying is great for utilisization of the aircraft that otherwise sits on the ground between VA2 and VA1, but the big question remains where is the 4th aircraft gonna go? My bet is on Phuket and MEL-LAX. HND and JNB to come online with aircraft 5 (actually aircraft 7) in Q3 of 2010
