Welcome! There are folks on here from all over the world, several from Australia. There is a lot of history here too. Lots of answered questions you will find in searches. If not, ask away. Glad to help.
That is some special work for a special day. Oh to have something like that to look back on in later years. Wishing I had something like it. Great job. Thanks for explaining how you put the lettering on there.
Looking good. That is the setup for stamps that I had when I started. Added a second on for a total of 8 feet of drilled holes. then changed again to accommodate more stamps, etc.
