Australia

Country Code: 61
International Call Prefix: 0011

Telephone numbers in Australia consist of a single-digit area code (prefixed with a '0' when dialling within Australia) and eight-digit local numbers, the first four, five or six of which specify the exchange, and the remaining four, three or two a line at that exchange. (Most exchanges though have several exchange codes.) Within Australia, the area code is only required to call from one area code to another.

Australia is divided geographically into a small number of large area codes, some of which cover more than one state and territory. Prior to the introduction of eight-digit numbers in the early to mid-1990s, telephone numbers were seven digits in the major capital cities, with a single-digit area code, and six digits in other areas with a two-digit area code. There were more than sixty such codes by 1990, with numbers running out, thus spurring the reorganisation.

Following reorganisation of the numbering plan between [[1994^[1]]] and 1998, the following numbering ranges are now used:

National numbers have no geographic significance. Other numbers relate to a particular telephone service area.

However, allowances are made for regional variations; sometimes the codes do not strictly follow state borders. For example, Broken Hill in New South Wales uses the 08 area code, due to its closer proximity to Adelaide than the state capital Sydney, and the Broken Hill area's inclusion in the Australian Central Standard Time zone. The previous area code for Broken Hill was (080). Other examples include towns in Southern New South Wales close to the border with Victoria that use the 03 (Victoria and Tasmania) prefix, including: Balranald, Wentworth and Deniliquin). Some parts of the Tweed Coast of New South Wales have an area code of 07 followed by a subscriber number of 55xx xxxx (and new numbers 56xx xxxx). This means it is the cost of a local call to phone the Gold Coast in neighbouring Queensland, since the metropolis covers both sides of the NSW/Qld border. It is also a local call to adjoining NSW 02 667x xxxx numbers from these areas, and other southern Gold Coast exchanges (07 prefix numbers must dial the 02 to access these).

East Timor

Country Code: 670

Until September 1999, East Timor formed part of the Indonesian numbering plan, using the Country Code +62, followed by area codes for the two largest cities, Dili (390) and Baucau (399). Following the violence in the wake of Indonesia's departure from the territory, most of the telecommunications infrastructure was destroyed, and Telkom Indonesia withdrew its services from East Timor.

A new country code +670 was allocated to East Timor, but international access often remains severely limited. A complicating factor is the fact that 670 was previously used by the Northern Marianas, with many carriers not aware that the code is now used by East Timor. (The Northern Marianas, now part of the North American Numbering Plan, use the code 1 and the area code 670.)

East Timor now has a closed numbering plan; all subscribers' numbers are seven digits.

Telephone numbering in East Timor is as follows:

Mobile: 72X-YYYY 
Service Numbers: 721-XXXX
Fixed: 32X-YYYY (numbering range in Dili)  
Government Departments: 333-YYYY 
Ambulance Service: 110
Fire Dept: 115
Emergency: 112
International access code: 00

New Zealand

Country Code: 64

Since 1993, land-line telephone numbers in New Zealand consist of a single-digit area code and seven-digit local numbers, the first three of which generally specify the exchange and the final four a line at that exchange. The domestic long distance prefix is '0'.

The dialing plan used in NZ reflects the national structure implemented by the New Zealand Post Office prior to the privatisation of the telecommunications services (and the creation of the Telecom New Zealand corporation). Domestic phone numbers with a first digit in range 2-8 are generally managed by Telecom. Phone numbers beginning with 9 are usually those from other companies, for example TelstraClear. These allocations were firm until April 2007, whereupon full number portability was introduced; numbers can now be moved between carriers. [1]. There are currently no regions issued numbers starting with 1 - except for the national emergency services access number, '111'.

There are five regional area codes in use for landline calls, For example, a domestic toll call destined for a South Island location requires the dial prefix '03', being domestic-long-distance + 3 for the South Island.

Mobile phone numbers are prefixed with 02, followed by one digit and the subscriber's number, which is either six, seven or eight digits, dialled in full, e.g. 021 xxx xxx or 027 xxx xxxx. With the introduction of number portability the number prefix is no longer a sure indicator as to the terminating network, but the following table lists the "default" mobile numbering prefixes:

Free call services generally use the prefix 0800 (via Telecom NZ) or 0508 (via TelstraClear), while local rate (usually internet access numbers) have the prefix 08xx. Premium rate services use the code 0900 followed by five digits. Neither of these are accessible internationally.

The International dialing prefix is '00', though other prefixes are available (i.e. 0161, for discounted rates, or 0168, for access to USA 1800 numbers).

To dial into New Zealand from overseas, the leading 0 should be dropped from all area codes. (For example, an 021 xxx xxxx number would be reached by dialing +64 21 xxx xxxx).

Papua New Guinea

Country Code: 675

Telephone numbers in Papua New Guinea consist of a seven digit national number, which is used for fixed, mobile and special rate services. There are no access codes for trunk services.

The international access code is '00'.

Broadly numbers are allocated to the following categories:

    0xx(x)   = operator services
    180 xxxx = free call services
    188 xxxx = local call services
    2xx xxxx = satellite telephones
    3xx xxxx = Port Moresby/Papua Region
    4xx xxxx = Lae/Morobe region
    5xx xxxx = Mount Hagen/Highlands region
    6xx xxxx = Daru/Fly region
    69x xxxx = AMPS mobile (no longer in use)
    68x xxxx = Mobile GSM
    7xx xxxx = Goroka/Eastern Highlands region
    8xx xxxx = Madang/Sepik region
    9xx xxxx = New Guinea Islands region
