|The Hon. Tanya Plibersek MP, Sydney by ACON Online|
Based closely on the Bill that was voted down in 2012, Plibersek has the support of Labor's caucus to introduce the private members bill.
Plibersek has indicated she will only introduce the bill if Prime Minister Tony Abbott allows all Liberal MPs a free, conscience vote as opposed to a Party bloc vote.
Without such a commitment, a new bill seems unlikely to pass.
The 2012 Bill was soundly defeated 48 votes to 92.
