What are some Australian Postal Codes? need help now.?

My cousins lives in Sydney and i need to send her a letter. anyone no the postal code?

Sydney is 2000. If you visit the Australia Post site, you can search for her suburb
http://www.justweb.com.au/post-code/sydney-postalcodes3.html It depends where in Sydney
It will depend on what suburb. Sydney city is 2000. Do you know the suburb? If not 2000 should get it to her but it's most likely not the right post code.
Which suburb do your cousins live in? I know that all of Sydney's postcodes start with a 2.
Sydney's CBD is 2000 or 2001. Sydney has many suburbs which have different postcodes. Do you know which suburb it is? You should use this tool from Australia Post to find out: http://www1.auspost.com.au/postcodes/
Sydney is HUGE with hundreds of post codes. Go to www.austpost.com.au then postcode finder and put in the suburb, it'll bring up the post code.
where in sydney? There are different postcodes for each suburb. CBD- 2000 Coogee- 2034 Clovelly- 2031
