On 5 December 2006, Allison introduced into the Senate a bill titled the Cluster Munitions (Prohibition) Bill 2006, which, if enacted, would prevent Australia from using, possessing and manufacturing cluster munitions. Two months earlier, she had travelled to Lebanon to survey the damage caused by cluster munition use in the 2006 Israel-Lebanon War. Allison, a leading feminist in the Australian parliament, was among a cross-party group of female parliamentarians who introduced legislation into parliament in 2006 which effectively legalised the supply of the abortion pill RU486. She advocated for federal government funding for public schools and nuclear disarmament.
