Choosing and Using a Call Sign After a Move
A standard licensee, VK2QRP, moves from New South Wales to Queensland and takes his radio equipment with him. He continues to sign VK2QRP from his new home. He also sometimes operates portable from a park in Queensland and, on a trip to Tasmania, operates from a holiday house for two weeks. He has heard that call signs encode the state or territory, that portable operation uses a suffix, and that a visiting operator may use a different prefix. He wants to know which call sign to use at home, in the park, and in Tasmania, and whether he must apply for a new call sign after moving.
1. May VK2QRP continue to use his existing call sign after moving to Queensland, and what should he check?

In Australia the digit in an amateur call sign broadly reflects the state or territory of the licensee's address, but the call sign is issued to the licensee and is not automatically invalidated by moving. The licensee should check the current requirements with the regulator about whether a new call sign must be applied for or whether the existing one may be retained, because the answer depends on the issuing rules in force. He should not assume that moving silently changes his call sign, and he should not invent a new one. The safe course is to confirm the position before operating from the new address, then use whichever call sign the regulator confirms is correct.
2. How should he identify when operating portable from the Queensland park?
Read the worked answer
When operating portable, he should identify with his call sign followed by the recognised portable indicator, commonly '/P', and should be clear about the location if asked. The purpose is to tell listeners the station is not at its licensed home location, which matters for coordination and for anyone trying to contact him. He should use the call sign that is valid for him, not change the digit to match the park's state unless his licence actually specifies that. He should identify at the start and end of contacts and at reasonable intervals, and should follow the local band plan for the park.
3. What call sign arrangements apply when he operates from the Tasmanian holiday house for two weeks?
Read the worked answer
Short-term operation away from home is generally treated as portable or temporary operation rather than a change of licence address, so he would normally continue to use his own call sign with a portable indicator. The two-week stay is not a permanent move, so it does not by itself require a new call sign. He should check whether any local requirement applies to visiting operators and should identify clearly. If the stay became permanent, the position on the call sign digit could change and he should confirm with the regulator. The reasoning is to distinguish temporary portable operation from a change of licensed address.
