Alias not working for tag in org-mode


Suppose I have a page called “Australia” and an alias for it “AUS”. I have noticed that when I use markdown syntax to label a todo item with the alias, i.e. “#AUS”, the tag correctly links to the page “Australia”. However, if I use org syntax (I am currently using the “org” option in settings) :AUS: it does not work and takes me to a new page called “AUS”. Is this expected behaviour?

Also, I would have thought that using # to create a tag would automatically convert it into org syntax, but that seems not to be the case. I saw this was also mentioned here: Tags in org mode · Issue #1174 · logseq/logseq · GitHub.
