Alternative flags

While in Australian waters an alternative flag may be flown at times when a flag is required to be flown (the relevant times are listed below). However, at those times the ship must be currently entitled to fly the alternative flag.

The alternative flags are:

(This ensign may be flown as an alternative flag if a warrant from Her Majesty or the Admiralty was in force authorizing its use by the ship before 26 January 1982, and section 73 of the British Merchant Shipping Act 1894 is in force at the time the ensign is used as an alternative flag, and the flying of the ensign at the relevant time is authorized by the warrant.)

While in waters outside Australian waters, no alternative flags are permitted to be flown.

Positions at which a flag is to be flown

The national flag or red ensign must be flown at the stern, or if this is not practicable because of the ship's design or use, as near as practicable to the stern. Where there is no stern, the flag must be flown in a position approved by the Registrar.

Only one of the flags mentioned here (national flag, red ensign or an alternative flag) may be flown at any one time.
