I'm in quite a similar situation to you! I'm 20 living in Australia as well and going down a similar path that you described in number 2.And so without a doubt I would say for you also the second choice. I'm not sure about what your ultimate goal is but I think with most paths in music, the wisest idea would be to be keep up a performing career as long as you can, to keep building your reputation, experience and knowledge. In turn you will also be more equipped to teach at a higher level.I've always been told that the standard of music education here in Australia is at a lower standard compared to overseas, so if you really want to be good and put yourself out there then you must go overseas. 20 is still quite early to think about settling down already and as you've already finished a bachelor's you are already ahead! What you can do in addition to attending festivals/master classes is to enter competitions and eisteddfods, and also teach privately at home. This is exactly what I'm doing at the moment - I'm taking a 'gap year' this year (I did 2 years of a bachelor of music but have dropped out of that because my experience there left something to be desired...) and hoping to join as many festivals and competitions as I can in preparation for an audition in November for overseas conservatories. We're in this together ! heheAt this age we are still young, push yourself and get out there while you still can! (assuming that you will have financial support during this). If you want to do music I think your goal should be to improve yourself as much as possible before you start to settle down and think about earning a living. It's the same for other careers as well - you gotta finish your education and study well before you start transitioning to full-time paid work.Would love to know what you eventually decide to go with though, will be following this thread since we are in similar situations
