Hey... Yeah everyone told me oboe was difficult.... but I picked it up soooooooooooooo easily..... It was like a duck to water... To me I thought this is impossible.. it seems too easy to play.. but yeah... Probably cause I play Clarinet and Flute and now Oboe... but yeah.. i found it really easy to start on it... Soo your studying for your AMEB... well yes there is no books out there for it... but there is a scale book.. but the syllabus has a selection of songs... just ask your teacher.. he/she will tell you what music you need to buy...

Hope I was of Help

Cheers
