Snork Maiden's Tax Assessment

Just got the tax assessment and the amount payable is less than half of what I expected: $A301.45. not payable till 23 November either and conveniently payable by BPay too.

I had the wrong tax free threshold (too low) and maybe other mistakes in computing the tax payable. I did have the correct taxable income and offsets. I calculated these things correctly on my own tax calculation.
