Any legal issues and the propriety of ASIS's activities are overseen by the Inspector-General of Intelligence and Security (IGIS), who reports to the Prime Minister annually. ASIS's financial and administrative affairs are regularly audited by the Australian National Audit Office (ANAO).
The time before a bankruptcy is removed depends on your individual chapter of bankruptcy filing. If you filed a Chapter 7 Bankruptcy, the bankruptcy will be removed from your credit report 10 years from the date you filed. If you filed for a Chapter 13 Bankruptcy, the bankruptcy will be removed 7 years from the date you filed; not from the time of discharge. Keep in mind that a Chapter 13 bankruptcy involves a debt repayment plan so typical discharges occur 3-5 years after filing.
One thing to note is that creditors and credit bureaus report bankruptcy dismissals differently - the time period can be anywhere from seven to ten years. That said, most other negative data and remarks on your credit report do drop off after seven years from when it was placed on the report.
