Since the pandemic very few companies here have real delivery service. It is the same for just about any delivery. I live in an apartment building and the delivery person will just drop it on the floor inside the door. They don't ring the bell or knock. It's not easy for those of us who can't move large things on our own.The last time we bought a mattress (and it was a few years ago) the store delivered the new mattress, brought it upstairs to our bedroom. Carefully took the plastic shipping cover off, fitted it over the old mattress and took it away. Part of the delivery service. This is no longer done, or not done in Australia?
Recently I happened to run into a delivery person who had a large package for me and he was so nice he actually brought it up to my door. He told me that since they are no longer going to the door he delivers almost twice as many packages.
I think it is just an excuse by companies to make more money by doing less.
