The most substantive change that we are making in this legislation is the introduction of a planning and preparation offence. As was mentioned in the House yesterday, a High Court decision of last year, where a High Court judge essentially said, "The case before me, while maybe concerning, I cannot bring or make a judgment on in terms of planning and preparation, because there is a gap in the legislation, where it might be an offence to carry out an attack, but the statutes of this country do not include an offence in terms of the planning and preparation." This particular offence was one that was recommended very highly by the royal commission of inquiry into the mosque attacks. It brings us into line with similar countries which we compare ourselves too—the likes of Australia and the United Kingdom—to make sure that we do have offences where the authorities can bring about a case to show that there is the three pillars of a terrorist attack, in terms of motivation and intent and purpose, and where a number of elements have come together with that planning and preparation, that now, once this bill is passed, the authorities will have the ability to bring charges in that respect.
