on the Optus network in Australia. This is predominantly used for MobileSat and Thuraya mobile satellite services. These numbers were allocated in December 1992: 222,000 with the rest "spare". The prefixes 0141, 0142, 0143, 0145 and 0147 are set aside for satellite systems; the rest of the 014 prefix range is currently not allocated to any other service type. There is not a lot of demand for these services, and many satellite phones now have normal mobile phone numbers (prefix 04), so it is not likely for the entire 014 range to be allocated to satellite services. Location independent communications service (0550) These numbers are designed for VoIP (Voice over Internet Protocol) systems, where they work like a fixed number but not allocated on a geographical level. It is possible that LICS numbers will be absorbed into mobile numbers in the future, as they provide similar features. Indeed, the July 2012 variation of the numbering plan allocated the rest of the 05 range to digital mobile numbering. Data numbers (0198) All calls to 0198 numbers are a "local call" cost like 13 and 1300 numbers but are used for Internet service provider access numbers.

(See below) However, the 0163 prefix is still allocated for use with pagers. This was reduced from 016 in a variation to the previous numbering plan. As of March 2011 only 1000 numbers were allocated, and by the end of 2012 there were none allocated. Non-geographic numbers (domestic use) The following codes are not generally dialable from international points, but used in domestic dialling: 000 – Emergency (Police, Fire, Ambulance) 106 – TTY emergency (for the hearing-impaired) 11 – Community services 1100 – Before You Dig Australia (to prevent inadvertent damage to underground cables or infrastructure) 112 – Alternative access to Emergency Services (Police, Fire, Ambulance; diallable from GSM mobile phones only) 119x – Information services (e.g. 1194 was time (no longer available from 1 October 2019) and 1196 was weather (no longer available from 1 October 2019)) 12 – Network services 1221 – International faults reporting service 1222 – Call costs and enquiries service 1223 – Directory assistance 1225 – International directory assistance 123x – Premium operator services (e.g.
