Thank you, Senator Sterle, for those comments. I'm instructed that currently the scope of background checks in the act is limited to only preventing unlawful interference with aviation and maritime infrastructure. To go to the issue that you have raised, the bill will provide for the strengthening of the ASIC and MSIC schemes by ensuring that those with serious criminal convictions or links to organised crime do not exploit the schemes to access the secure areas of our airports, seaports and offshore facilities.
