When New South Wales parliament debates a bill this week to ban sex-selective abortion, it will be responding to a problem that researchers say barely exists in Australia. The proposed legislation would impose professional misconduct charges and strip indemnity insurance from health practitioners who perform abortions based on fetal sex—a measure that sounds reasonable on its surface, until you examine what the evidence actually shows.

The case for such a ban rests on fragile ground. The South Australian Law Reform Institute found "little, if any, evidence that abortions purely on the basis of gender are a real issue in Australia." A 2020 New South Wales review similarly concluded that sex-selective abortions "are rarely performed for the sole purpose of sex selection." Proponents of the bill point to a recent study suggesting the practice may occur among certain migrant communities, but the study's own authors describe their findings as merely "indirect evidence" of a skewed sex ratio at birth. They explicitly state their work "does not establish causality"—meaning even their own research cannot prove sex-selective abortion is actually happening in Australia.

Yet the law already varies by state. South Australia explicitly prohibits the practice, while New South Wales previously passed a statement of parliamentary opposition to it during its decriminalization debates. No other state or territory has specific provisions. This is the landscape into which new legislation is being inserted—not because of documented harm, but for other reasons entirely.

Legal experts warn the bill would create serious practical problems. The South Australian Law Reform Institute has cautioned that such prohibitions would restrict and delay access to time-sensitive care while proving "unworkable and unenforceable." The practical difficulty is straightforward: fetal sex can be determined through non-invasive prenatal testing (a blood test taken between 10 and 14 weeks of pregnancy, used by around 25–30% of pregnant people and costing $500 to $800 out of pocket) or through routine ultrasounds at 20 weeks. Creating legislation that polices the reasons behind abortion decisions—rather than the decisions themselves—runs counter to Australia's hard-won principle that pregnant people are the authorities on their own pregnancies and are no longer required to account for their decisions to medical professionals.

Researchers and advocates identify the bill as part of a broader strategy. Sex-selection amendments are a well-documented anti-abortion tactic designed to foment stigma and discourage health practitioners from providing abortions. This bill is one of several currently before state parliaments aiming to limit access to abortion care, part of a coordinated effort to erode abortion access and contest the principle that abortion is health care itself. The parliamentary process becomes a mechanism to advance narratives that frame abortion as morally indefensible—evident in the bill's language, which refers to "unborn babies" rather than fetuses, "mothers" rather than pregnant people, and doctors as "abortionists."

As Australia continues to recognize reproductive autonomy as foundational to both gender equality and health care, this bill appears to move in the opposite direction—creating new restrictions to address a harm that evidence suggests is not occurring.
