What rules would you use to validate an Australian Phone Number?

What can I do to comprehensively validate an Australian Phone Number? I need this for an application I'm writing. You can assume it is dialed from within Australia. I want to use a white-list approach.

Here are my rules so far (after removing any whitespace):-

Starts with 13 and is 6 digits long
Starts with 1300 and is 10 digits long
Starts with 0 (but not 0011 as this is international dialing) and is 10 digits long
Starts with +61 followed by 9 digits
Starts with (0_) followed by 8 digits (where _ is 1-9)

Is there anything I have missed?

Area codes are required as we may be sending a fax from our fax server in one state when the user is in a different state.

(I'm not asking how to make a regexp out of the above rules, but if those rules are correct).

I did a similar thing a while ago. The Wikipedia page that unthinkableMayhem mentioned was a great starting point.

As of a year ago, my rules looked something like:

02[3-9]\d{7}  NSW/ACT
03[4-9]\d{7}  VIC/TAS
07[3-9]\d{7}  QLD
08\d{8}       SA/NT/WA

04[\d]{8}     Moblies  04x[123] = Optus,  04x[456] = Voda, 04x[0789] = Telstra

0500[\d]{6}   Find me anywhere server
0550[\d]{6}   VoIP
059[\d]{7}    Enum

13[\d]{4}     Local rate
1300[\d]{6}   Local rate

1800[\d]{6}   Free call

0198[\d]{2}   Data networks (local call anyway I think)
0198[\d]{6}

190[\d]{7}    Premium rate

0011 is not the only international access code. For example, calling overseas by fax you should use 0015 - it avoids the voice clipping effect of compression, which is not good for fax (or data, if you happen to be using a modem). My office phone database has 0015 prefixes on some international fax numbers. There are other special purpose international dialling codes as well.

And I still see mobile phone numbers written as (0411) 123 456

For a definitive list, try https://github.com/googlei18n/libphonenumber

Google's common Java, C++ and JavaScript library for parsing, formatting, storing and validating international phone numbers. The Java version is optimized for running on smartphones, and is used by the Android framework since 4.0 (Ice Cream Sandwich).

You can test it here: https://rawgit.com/googlei18n/libphonenumber/master/javascript/i18n/phonenumbers/demo-compiled.html

This was way overkill for my little job, and I generalised my test, but that library will allow you test you rules :)

I'd be tempted to remove the parentheses as well. I still see phone numbers written like "(0212) 34 5678" every once in a while.

Are there still 008 numbers in use? How about 1800? I think that's a valid prefix similar to 1300 nowadays.

This is probably what you are after:

Telecommunications Numbering Plan 1997 Establishes a framework for the numbering of carriage services and for the use of numbers in connection with the supply of carriage services, specifies the numbers for use in connection with the supply of carriage services, and establishes a framework for the allocation and portability of numbers.

It's a brief 261 page document that contains all you need to know :)
