From the excellent Jonathon Mott at UBS:
Single name exposures (Bad Debts) to dominate the 1H16 Results
The last few months have seen a handful of large, high profile corporate collapses. In some cases the companies have entered administration, others are in ongoing discussions with their banks. While underlying credit quality of the Australian banks remains solid, these exposures will require a substantial increase in provisions which is likely to lead to a material rise in BDD charges with the 1H16 Results in early May.
