By the way in answer to your tax question the tax on the income statement relates to the anticipated tax on revenue. It's recorded on the income statement on the year revenue is recorded (year the work is done) but actually paid to the ATO when the fee is received.

Here's a comparison of movement in the numbers:

	Column 1	Column 2	Column 3	Column 4
0	000	2017	2016	2015
1	Tax expense	-5335	-3604	…
2	Tax paid / Benefit recieved (cash)	-108	516*	…
3	Deferred Tax Liability	65259	59990	56470
4	============	=====	=====	=====
5	Change in Deferred Tax from prior year	5269	3520	…
6	Tax Cash paid + Expense	5227	3604	…

*Note that the tax benefit from 2016 doesn't count towards the liability as this is money in not out.

So as you can see the yearly change in the deferred tax liability matches up closely with the tax expense adjusting for any money paid to the ATO. Not sure why the numbers don't match exactly but this may be a timing issue from when the report is run.
