Hello and welcome back..... The NSW GRN (Government Radio Network) is a huge Digital Radio Network that spans across NSW & the ACT....

The Digital Network is also known as - APCO P25 Phase 1 network and has more than 27 Government agencies.

## Updated 28/05/2015 - Opera House site added


  • Ambulance Service of NSW
  • Fire and Rescue NSW
  • NSW Rural Fire Service
  • NSW State Emergency Service
  • ACT Emergency Services
  • Department of Attorney General and Justice
  • RailCorp
  • Roads and Maritime Services (formally Roads & Traffic Authority and NSW Maritime)
  • Sydney Ferries
  • Department of Corrective Services
  • NSW Department of Juvenile Justice
  • National Parks and Wildlife Service
  • Ausgrid
  • Endeavour Energy
  • Hunter Water Corporation
  • Sydney Water
  • Sydney Catchment Authority
  • Sydney Ports Authority
  • Central Tablelands County Councils
  • Sutherland Shire Council
  • Australian Broadcasting Corporation
  • Chevra Hatzolah (Jewish Community sponsored and staffed medical response)
The network is also used by other government departments and discrete law enforcement agencies.

NOTE - Most POLICE use a Encrypted Digital transmission and can NOT be monitored.......
              Some country police may still use analogue and can be monitored.


The network is a digital 9600 bps Project 25 (commonly referred to as P25 or APCO-25) Phase 1 trunked radio system operating in the UHF band between 403MHz and 420MHz in 12.5 kHz steps.
End user equipment is currently supplied mostly by Motorola and consists primarily of the XTL-5000 (mobile) and XTS-5000 (hand-held) two-way radios (although Tait Communications and Simoco radios are also authorized for use). Encryption is supported and used by some agencies on the network.



Basically, it means to listen to this network you need to buy a Digital scanner.

You will need to program the radio using the GRN CONTROL CHANNELS (See Below) from a tower in your area.
The radio reads the information from these control chs and decodes it displaying the user 'Talkgroup ID" & audio.

1 or 2 control channels for every tower - C =  primary control channels (red)
                                                                  A = alternate control channels (blue)
You will need to enter both these channels into your scanner when programming.
