I'm in Melbourne, Australia and I just received my Axe-Fx Ultra from the US today.
I didn't have to pay any duty - just GST and the customs processing fee.
According to the customs import schedule, there's really nothing that completely describes the Axe-Fx.
The closest I found was "synthesiser" - which is exempt from duty.
For the form B374 customs import declaration, the tariff classification for this is 92071000 and the Stat Code is 47.
Surprisingly, the whole process was quite painless and quick.
