One of the great advantages of DMR is that repeaters are designed to be linked together directly via IP.  This allows interconnection of repeaters in the next suburb, or on the other side of the world…

A number of DMR system designers who were also amateurs realised the potential offered by DMR for wide area connection of amateur repeaters.  They formed a world-wide network of more than 500 interconnected DMR repeaters, across 44 countries, including Australia and New Zealand.  There are more than 60,000 registered amateur DMR users.

Australian DMR amateur repeaters are located in most States/Territories.  

All operate in the 438/9 MHz (70cm) UHF band, apart from Darwin and Central Coast NSW, which use 146 MHz (2m) on VHF.
