The lams can be restacked in different patterns. This changes the inductance -- while the higher the inductance, the lower the fidelity, this is relative, they work and sound great at all levels.
Anyway, cores are 80% permalloy (nickel) and butt stacked are ~20H (impedance=2K5 @ 20Hz, and over 100K at 1KHz) and fully interleaved are ~170H (over 20K at 20Hz and over 1M at 1KHz).
Frequency response on the low end depends on how they are stacked, and is over 200K on the high end.
Current rating is ~0. If your offset is much more than a few minivolts, you'll need a DC blocking cap.

But, short answer: I can ship to Australia. Shipping would be up to you. USPS is the cheapest and would cost between $10 and $20. Your risk of loss due to no tracking. UPS or FedEx can be insured and tracked, but it is a lot more expensive. Also, actual sale value will be written on the package for customs.
