I've got the standard red, pink, green, white and black pepper corns. The black pepper corns are the only ones in a mill. I replaced our old hand operated mills (S&P) at Christmas with new hand operated ones. The old one had screws in the bottom that well the wood had rotted around screw and the grinding mech fell out. The new one is also wood. The old ones were over 2 decades old, so we'd no issues replacing them with more wooden ones . Ironically they were made in England, not Australia.
The other pepper I have is a mountain pepperberry. It's a native Australian berry with a peppery taste ,so you get a fruity taste initially followed by that pepper taste. It's a dried fruit just like pepper corns.
