This is not Australia Post at fault but the fact that there are many cheats Ebay . I have a large ecommerce site and would get 1 in 500 say that an untracked itme has not arrived or is late.
On Ebay it is a hundred more times likely to happen .
Ebay's policies has created a culture that buyers can lie and claim so easily.

We have had a couple of online 'shoplifters' taking advantage of un-tracked low volume items mailed as letters. We are still sending items by letter post and delivery outstrips parcel post by days due to the lower letter volumes.

One trick we now do, is stick a DIY barcode sticker in the top left corner which gives the impression of a 'Tracked Letter'. Not one has been 'lost' since...

Just an update.....I received a message from buyer yesterday letting me know that it finally arrived yesterday.  I posted it on from Sydney on 21st September and it was delivered to Melbourne 23rd October.  That is ridiculous! The buyer asked me for my paypal address and resent the money that I had refunded her.  

What an awesome buyer! She could easily have said nothing, but instead, she is honest. Shame all buyers aren't like that!

 

It's very hit and miss with Victoria at the moment. A few weeks ago I posted to parcels from central NSW to Vic, on the same day. One arrived in a few days, the other was about 3 weeks from memory.

yep it bad sending VIC to VIC I am getting packages from the USA faster than it takes to send a letter or package around VIC atm.

I got a small parcel from the UK faster than a parcel from one Melbourne suburb to another Melbourne suburb....and they were far from one side ot Melb to another.  Grrrr.

Australia Post loses no less than 1% of my untracked items . This has been consistent over the last 6 years for me. It results in financial losses, disputes & negative feedback. These statistics are not included in the Australia Post performance reports. If  Australia Post *delivers" 12 billion letters annually, 120 million don't make it. 

 

How on earth do you know that AP is losing your letters ?  It could very easily be dodgy buyers opening a dispute with eBay knowing that they will automatically win that dispute because you can't prove that the item was even sent in the first place.

Exactly

 

The OP has even left false positive feedback for one such buyer

 

Most likely there are many others after a quick freebie too
