4.1 Australian VK Callsign Scheme & State/Territory Call Areas

Decode the ordinary format

In the illustrative call sign VK3ABC, VK is the Australian prefix, 3 is the area digit and ABC is the individual suffix. ACMA generally assigns the digit corresponding to an amateur operator’s state or territory of residence at first assignment. It may consider a different area on application. Read the number as an assignment clue and ask for the present location if it matters to the contact.

Keep the distinction between residence and operation

Suppose the operator assigned VK3ABC moves to Queensland. ACMA policy allows them to keep VK3ABC. If they want a new Queensland call sign, they can apply to ACMA and pay the applicable fee. They can also keep their current call sign after gaining a higher qualification. ACMA Assist is the online channel for managing the assignment and contact details.

When operating portable, ACMA guidance allows a location description after the assigned call sign. Its example VK6HR portable 8 communicates an assigned Western Australian area and current portable operation in the Northern Territory. Say the assigned call sign at the required times. Keep the portable description additional to the sign.

Match a call sign to an actual assignment

Section 7 gives effect to Class Licence Schedule 4. Clause 1 covers applying to ACMA, including the approved form or method and any applicable charge. ACMA considers its published policy and the ITU Radio Regulations. It notifies the person in writing of the assignment. The obligation to assign a call sign when the criteria are met does not guarantee an applicant's preferred combination. Check availability before requesting a particular sign and use the call sign ACMA actually assigns.

The public class-licence call sign register shows the sign, its status and the qualification level for an assigned entry. ACMA does not publish the holder’s personal contact details in that register. For an assigned repeater or beacon, use the Register of Radiocommunications Licences. A sign’s presence in either register helps explain what it identifies. Check the applicable authorisation separately before selecting a frequency, power or mode.

Apply the territorial conditions

Class Licence section 12(7) limits use of an assigned VK0 call sign to the territory defined in the Australian Antarctic Territory Act 1954. Under section 12(8), VK9 can be used only in an Australian external territory other than that territory. ACMA lists Norfolk Island, Christmas Island, the Cocos (Keeling) Islands and Heard and McDonald Islands among its VK9 examples. ACMA expressly excludes Lord Howe Island from VK9 assignment because it is outside that external-territory category. These are legal conditions on the use of the specific assignments.

The call sign of an assigned repeater or beacon follows the station’s licence. ACMA says these usually use the pattern VK plus the area digit and a suffix starting with R. For a club call sign under the Class Licence, ACMA requires an Advanced-qualified representative for an application by the club. A club member operating on the club call sign follows their applicable frequency and power conditions. The call sign cannot itself expand those permissions.

Worked territory check. An operator holds an ordinary VK7 sign and a separate VK9 sign assigned for use on Christmas Island. Back in Tasmania, the operator uses their ordinary sign. The fact that ACMA allows retention of a VK3 assignment after moving to Queensland does not extend to using VK9 outside an eligible external territory. Before a trip to the Australian Antarctic Territory, check the VK0 assignment process and the evidence of posting requested by ACMA. For VK9, the policy distinguishes evidence of residence on major islands from an authorisation letter for remote territories.

For a vehicle, vessel or aircraft contact, ACMA describes the usual spoken additions as mobile, maritime mobile and aeronautical mobile. These tell the listener about the operating situation. A portable suffix indicating a different state and the selection of a separately assigned special prefix are different decisions.
