新南威尔士州宣布启动自1996年塔斯马尼亚港口大枪击案以来最大规模的枪支回购计划，但昆士兰州、维多利亚州、南澳州和北领地均拒绝参与[1]。新州计划于11月2日开始实施该方案，约50000名持枪证件持有人需交出枪支，大部分枪主最多保留4把枪，农民和运动射手可保留10把，预计共有约274000支枪支需要被交回以符合限制规定[1]。
昆士兰州卫生部长蒂姆·尼科尔斯表示，昆士兰州、维多利亚州、南澳州和北领地均认为枪支回购计划"在处理邦迪事件问题方面不是物超所值的"[1]。昆士兰州政府转而将关注点放在防止枪支流向犯罪分子和恐怖分子上[1]。由于拒绝参加全国回购计划，昆士兰州的持枪数量为114万支，仅次于新南威尔士州的116万支，这将使昆士兰州成为澳大利亚持枪数量最多的州[1]。
New South Wales has launched Australia's largest gun buyback program since the 1996 Port Arthur massacre in Tasmania, beginning November 2, with approximately 50,000 licensed firearm holders required to surrender their weapons [1]. Under the scheme, most gun owners must reduce their holdings to a maximum of four firearms, though farmers and sport shooters may retain up to ten [1]. Roughly 274,000 firearms need to be handed in to comply with the new restrictions [1].
However, Queensland and several other states have declined to participate in the national buyback initiative [1]. Queensland Health Minister Tim Nichols stated that "Queensland, Victoria, South Australia and the Northern Territory do not believe a gun buyback is value for money in addressing the Bondi incident" [1]. The Queensland government has instead prioritized preventing firearms from reaching criminals and terrorists [1]. With Queensland holding 1.14 million registered firearms compared to New South Wales' 1.16 million, Queensland will become Australia's most heavily armed state as New South Wales reduces its arsenal through the buyback program [1].
