Yes I do know all of these, as I actually work in the industry.

My problem is that Ebay have these policies etc, which clearly mean nothing to them, when I look and see so many people selling non compliant seats  that do not meet the Australian Safety Standards seats

Very hypocritical !!

I want to know how they get away with it ?

As this practice is Illegal !!!

They clearly have no ethics or morals where children and babies are concerned ....
