with the AUD approaching parity with the USD there's negligible difference.
Still seems very much like profitless prosperity, we'll never know the exact cost but let's say US$5 per test to the manufacturer plus a share of all other expenses are allocated against each test sold.

Even at 3 TIMES the present rate of sales those other expenses would amount to another US$4 or $5 each test, add the manufacturer's cost of US$5 and the all up cost per test would be US$10 or thereabouts even selling 2 million tests a year (3 times the present sales rate).

And we're selling to them for US$10 a test??
