The parcel service are part of the business or unreserved services provided by AP in competition with other competitors, whilst the letter service are part of its Community Service Obligations (reserved service) under the Act .

Whilst there are alternate services on the market, I imagine AP still do pretty well out of its registered post letter services, ie. legal documents that must be sent by a mail service such as registered post ie. eviction notices etc  I like the product as registered letters still remain one of the post products that has ($100) compensation built into the price for using service.

Who knows, maybe AP will eventually replace registered post letters with more financially lucrative products.

I don't think the legislation is compelling issue of receipts for proof of lodgement.
