There are AMAZING warmbloods at Yalambi Horse Stud in Western Australia, I’m not sure where you are from but the horses from Yalambi are amazing!
I am looking some up. I'll give you a gob of them, but check them out (like a tour of the facility) before contacting for lessons
Not too sure but look at some barns, they have should have some good warmbloods. Europe is where I found my warmbloods
