Given cash flow is everything for this company, I can appreciate your concerns about the working capital lemon being now squeezed dry with little wiggle room for further improvement.
However, you might have missed the $5m reduction in short-term provisions on the balance sheet.
This would in large part reflect the redundancy and restructuring charges that were booked to the P&L during FY12, but which only had the cash-related outflows occur in DH12.
So one could reasonably conclude, if one was so inclined (and I am), that OCF for DH12 is understated by some $5m.
As for contractor costs as a percentage of revenue, I wouldn't stress too much about this, as it is well within the historical range of natural ebbs and flows:
Just as this operating cost metric has risen in recent financial reporting periods, its "counter-balance", Direct Employee Expenses as a % of Revenue, has fallen commensurately: DH06: 49.8 JH07: 55.6 DH07: 43.7 JH08: 43.0 DH08: 43.1 JH09: 45.1 DH09: 42.9 JH10: 45.7 DH10: 46.9 JH11: 51.5 DH11: 48.4 JH12: 48.0 DH12: 47.4
As you can see, these two cost metrics are almost perfectly out of phase (when the one is high, the other is low, and vice versa).
I think this is part of the normal corprorate pendulum of bringing resources in-house when they are scarce (during the boom period) and out-sourcing them when they are in abundance (the current situation).
At least, that's my interpretation of the well-established pattern.
