Former PM Tony Abbott reintroduced knighthoods and damehoods in 2014.
His controversial decision to grant Prince Philip a knighthood in January was widely seen as one of the factors which ended his term as leader.
Mr Abbott at the time said Australia was honouring the Duke of Edinburgh`s lifetime of "service and dedication", but later said the decision was "injudicious".
He was ousted as leader of the centre-right Liberal Party by Mr Turnbull in September.
