Did you realise there are letterbox standards for minimum mailbox sizes in Australia? And also for where to position various types of letterboxes?
You certainly wouldn't know it from a quick look up and down most streets! However, when you think about it, it makes sense.
As part of its terms and conditions of service Australia Post includes an appendix detailing letterbox standards for size, numbering and placement of your mailbox. If you don't provide a mailbox that is large enough to receive the anticipated volume of standard letters, or if your mailbox isn't easily accessible your postie may refuse to deliver your mail. I suspect this doesn't happen often, but it's better to be safe than sorry!
I believe the Australia Post standard is derived from the Australia New Zealand official standard, AS-NZS 4253-1994. If you make letterboxes to sell in Australia I recommend you purchase this standard to make sure you conform.
And, before you buy, make or install your next letterbox make life easier for your postie by conforming to the Australia Post standard. You'll also be helping make your mail delivery service speedy and reliable.
Sensibly, the Australia Post recommendation is to have the right size letterbox for the amount and type of mail you typically receive. If your household orders small packages online you should factor this into your choice of letterbox.

The aim is to allow the postie to deliver mail without having to get off his or her bicycle or motorbike...
