Answer:
Step-by-step explanation:
As of my last knowledge update in January 2022, I don't have access to specific details about the Privacy Act 1988 amendments or penalty unit changes after that date. It's important to note that laws can be amended, and penalties can be updated.
As of my last update, I can't provide information on breaches punishable by 2000 penalty units as of October 21, 2023. I recommend checking the latest amendments or legal resources for the most up-to-date information on the Privacy Act 1988 and associated penalties. Legal databases, government websites, or legal professionals would be reliable sources for current and specific legal details.
