Sophie Mirabella's political career may have sunk at the last election, but the ex-Victorian MP resurfaced in Canberra on Sunday night for an exclusive dinner with Prime Minister Tony Abbott and former colleagues.

It comes after Ms Mirabella was appointed to the board of the government-owned naval shipbuilding firm ASC Pty Ltd, formerly the Australian Submarine Corporation, last December.

Mr Abbott and Ms Mirabella were joined by about 20 Coalition MPs for the dinner, including Treasurer Joe Hockey, Attorney-General George Brandis and Agriculture Minister Barnaby Joyce.
