This looks very similar to mine:
viewtopic.php?f=87&t=24524
I've been unsure as to what type it is and had a dig through the WA Flora database:
httpss://florabase.dpaw.wa.gov.au/search ... =melaleuca
They don't all have photos but what I came up with is M.macronychia, but I'm not totally convinced. It looks similar to M.hypericifolia as others have suggested so maybe it depends where the tree originates, WA or eastern states.
Mine is also yet to flower, and I think that would be the main dealbreaker.
Also try these:
https://plantnet.rbgsyd.nsw.gov.au/cgi-b ... =Melaleuca
https://vro.agriculture.vic.gov.au/dpi/v ... _melaleuca
They're from the NSW and VIC governments, but i couldn't find mine on there as I get stuck at flower descriptions
**EDIT** having said all that and having another look, I think your leaves are a little rounder
**EDIT2** the guy I got mine from just messaged me and said mine is m.violacea
