The Berejiklian government is considering reinstating a plum overseas posting more than two decades after it was axed because it was "a throwback to the colonial days".

The post of Agent-General for NSW, based in London, was abolished in 1993 after former Liberal minister Neil Pickard - who scored the role as a sweetener for losing his seat in a redistribution - was caught up in an expenses scandal.

Then-premier John Fahey told NSW Parliament on May 3, 1994 that "it was abundantly clear to me, to all cabinet and to all government that we no longer needed an agent-general's office in London".

"That was a throwback to colonial days – to the days when it was important to have garden parties and to participate in ceremonies. Quite frankly, [there was] little or no benefit accrued to NSW by participating in such a process," the then Liberal leader told Parliament.
