IT'S not another planet, but Doctor Who stars Peter Capaldi and Jenna Louise Coleman emerge from the Tardis on the other side of the world as they land beside Sydney Harbour Bridge.

The television duo are in Australia as part of a world tour to promote the new series of the BBC1 programme, which airs globally on August 23.

Glasgow-born Capaldi takes the helm from previous Doctor Matt Smith and it is said the 12th incarnation of the Doctor will bring a darker edge to the role.
