GB is right. Don't forget that a number of B767 routes were abandoned in the 90s that allowed more domestic flying. Routes such as PER/BKK, SYD/SGN and SYD/SEL to name three. Domestic needed some addition capacity to replace the A300s so the 767 was 'conscripted!. The units ex BA I seem to recall came after the Ansett collapse and were specifically for domestic use.
