> Do musicians in Canada, Australia, New Zealand and former British colonial possessions use the hemi, semi, demi names?

I did my first theory exam in Australia and learnt semibreves and crotchets etc; not to mention acciaccatura (grace note) and appoggiatura, my Italian favs. I think it's because the exams are similar to the Royal School of Music exams from England.
...by the time seventh grade theory had rolled around the required vocab was the least of my troubles!
