Are you ordering Chinese stuff from sellers that state their items come from Aus ?
Always check where an account is registered before buying.
Chinese sellers are known for misrepresenting location.
Also keep in mind those dates are only estimates given to eBay by AP and are probably AP's ideal estimates.

eBay doesn't have 'due dates', unless you're exclusively purchasing guaranteed delivery items. All other items have have ETAs.
ETAs aren't due dates. It stands for 'Estimated Time (of) Arrival'.
They are guidelines, not promises.
Where abouts do you live?
I have been finding the opposite, as all of my purchases have been arriving on or nefore the ETA, no worries.
A few years back i was having trouble with my post too, with mine lagging behind other areas. It came to a head when a friend sent out invites and mine arrived a week-yes a week!!-after friends in the next suburb had received theirs.
Go onto the Aust Post website and make a formal complaint. They will investigate & if the postal service in your area is a bit slack it might shake things up if they find head office looking into their performance.
It made a difference in my area.
And at the risk of being shot 
, I will say that ETA's may be only estimates but on the whole, they are very accurate. It's possible something might run a day or so late (though hasn't happened to me for a long time) but if you do buy something that goes well over eg a week over, open an item not received claim.
