To the OP,
Is Amazon.com available to you folks down-under?
A search on Amazon USA shows a few sellers as low as $3.95USD, for FP100c - $6.45USD, for FP3000b.
Maybe, use the Amazon link like a search directory, find companies that are selling at the right price,
then/or, contact those companies directly.
Another thought, can you access Japanese suppliers/retailers for a better deal?
PS: B&H Photo is a great company to do business with, I'm just trying to offer some other ideas for the future.
