Summarize this article for a 10 year old
Postcodes in Australia are used to more efficiently sort and route mail within the Australian postal system. Postcodes in Australia have four digits and are placed at the end of the Australian address, before the country. Postcodes were introduced in Australia in 1967 by the Postmaster-General's Department and are now managed by Australia Post, Australia's national postal service. Postcodes are published in booklets available from post offices or online from the Australia Post website.
Australian envelopes and postcards often have four square boxes printed in orange at the bottom right for the postcode. These are used to assist with the automated sorting of mail that has been addressed by hand for Australian delivery.
