GOVERNMENT OF THE COMMONWEALTH OF AUSTRALIA DEPARTMENT OF TRANSPORT & COMMUNICATIONS.

The Log shows a blue flag with a yellow disc bearing three black arrows. This livery was used at various periods by three lighthouse vessels built in 1963–1964 with names beginning Cape.

Loughran’s version has a narrower, more readily recognisable blue arrow device and is dated to the 1972 departmental merger. The arrows represent land, sea and air transport, the department’s three areas of responsibility.

The Cape Don funnel device has a thin dark-blue ring enclosing dark yellow, with the departmental three-arrow emblem and the surrounding inscription “DEPARTMENT OF TRANSPORT. AUSTRALIA”, both in dark blue inside the ring.
