The threat landscape that we as a nation are confronted with today is vastly different from that of five, 10 and 20 years ago. It's important to note that next month marks the 20-year anniversary of the terrorist attacks on 11 September 2001. The events in Afghanistan this week brought back the dark memories of that attack on the US people by foreign nationals. Those attacks changed the world and the way in which liberal democracies protect their citizens.

A lot has changed in those 20 years, but the need to protect Australia from attacks and interference by foreign actors has not. Technology has changed how the world works, and the massive rise of cyberattacks has created challenges which have seen the need to significantly increase the size of our intelligence agencies. The technology and geopolitics driving these changes can have serious ramifications on the effective functioning of our democracy if not properly acknowledged and addressed. Information is now more important to world affairs than at any previous point in history, as a result of those advances in data driven technology. Information is now the world's most consequential and contested geopolitical resource. It is a growing source of state power, where we have seen undoubtable evidence that many of our adversaries are expending more time, energy and resources to build and utilise this capability.

There are a variety of reasons for which states conduct intelligence, however, the foremost of these being to increase understanding and knowledge. The timely acquisition of intelligence can improve the quality of decision-making by reducing ignorance of the situation faced and enabling actions or decisions to be optimised. In order to keep Australians safe from foreign adversaries, we must be able to effectively inhibit external actors' ability to collect intelligence on Australia and our communities. This is a national security priority. As the methodologies of intelligence collection develop and change with the rapidly evolving technologies, so must our national security laws. The Richardson review was conducted as a response to this changing threat landscape to ensure that the legislative framework that we have in place effectively addresses the threat at hand. The Richardson review's examination of the legislative framework underpinning the national intelligence community is the first and largest since the Hope royal commissions considered the Australian intelligence community in the 1970s and 1980s. I would like to thank Mr Richardson for the important work he did on this. He has been, over his career, one of Australia's best public servants. That is no mean feat, especially when you see the calibre of our current bureaucrats, including the Director-General of Security and the Secretary of the Department of Home Affairs.

I too rise today to express my condolences on the tragic loss of life and devastation caused by the recent fires right across Australia but, particularly in my home state of Victoria.

In this place, I offer my heartfelt grief for all of those who have lost loved ones, friends, livelihoods and homes.
