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.
Another important date to be aware of regarding a bankruptcy is how long it will appear on a consumer credit report. It's not when the debts are discharged, but when you filed. For a Chapter 7, a notice is listed on your credit report for 10 years. For Chapter 13, it will show up for seven years. During the time the bankruptcy is being reported, your credit rating will be negatively affected, though as the years pass it will have less and less impact. When it's gone, it's over.
