It explains their history, meaning, typical users and important display requirements so you can identify the correct flag before ordering.

Which Australian Ensign Should You Fly?

Use the Australian Red Ensign for its official merchant-shipping purpose. Use the Australian White Ensign for approved Royal Australian Navy displays. Use the Australian Defence Force Ensign when representing the three armed services collectively, or the RAAF Ensign when specifically representing the Royal Australian Air Force.

The Australian Civil Air Ensign has tightly restricted use and generally requires CASA authorisation. For a general national, civic, business or private display, the Australian National Flag is normally the appropriate choice.

What Is an Australian Ensign?

An ensign is an official flag associated with a particular service, vessel or area of government activity. In Australia, ensigns are used to identify merchant shipping, the Royal Australian Navy, the Australian Defence Force, the Royal Australian Air Force and civil aviation.

The Australian National Flag remains the principal flag representing the nation. It takes precedence when displayed with Australian Defence ensigns and should occupy the position of honour in a formal multi-flag arrangement.

The Australian Army does not have a separate service ensign. It has the ceremonial role of protecting the Australian National Flag, while the Australian Defence Force Ensign represents the Army, Navy and Air Force collectively.

Before Ordering a Restricted Ensign

Permission requirements do not prevent legitimate organisations from purchasing the correct flag, but approval should be confirmed before a restricted ensign is displayed.

  • Australian White, ADF and RAAF Ensigns: Contact the relevant Defence service brand manager or service authority for permission and display guidance.
  • Australian Civil Air Ensign: Confirm that the display is authorised under the Civil Aviation Act 1988 or obtain permission from CASA.
  • Australian Red Ensign: Follow the applicable maritime protocol when using it for its official merchant-shipping role.

If you are purchasing for a government department, Defence-related organisation, RSL, museum, aviation organisation, maritime operator or formal ceremony, Evan Evans can assist with the product size and finish once you have confirmed the appropriate flag and authority.

Choosing a Size and Finish

These Australian ensigns are manufactured from durable 135gsm Trilobal knitted polyester for strong colour reproduction and lightweight flying performance. They are available in sizes ranging from compact 900mm × 450mm flags through to larger 3600mm × 1800mm formats.

Header with Loops is designed for traditional halyard flagpoles using loops and clips. A Vertical Sleeve slides over a presentation pole and provides a clean, formal finish for indoor displays.

The correct size depends on the flagpole height, viewing distance and display environment. Use our Australian flag size guide to compare common dimensions, or contact us for help with a formal multi-flag arrangement.

Official Guidance and Further Reading

Flag protocols and authorisation requirements are controlled by the relevant Australian Government and service authorities. Always check the current official guidance before displaying a restricted ensign.
