Mental illness is the number one complication of pregnancy and the postnatal period-not gestational diabetes, not pre-eclampsia. Up to one in five women will experience a diagnosable mental health condition during the perinatal window, from conception to one year after birth. Depression and anxiety are the most common, but the spectrum includes PTSD after birth trauma, obsessive-compulsive disorders, and rare psychotic episodes.

Despite these statistics, the healthcare system does not screen universally or fund treatment adequately. Australia has some excellent services, such as dedicated mother-baby units, but they are concentrated in metropolitan areas and the private sector. Public waitlists stretch for months.

A journalist and perinatal psychiatrist writes that we have romanticized the transition to motherhood, making women feel that admitting distress means failure. She hears versions of the same sentence weekly: “I thought I was just a bad mother.”

Screening exists but without a clear referral pathway. A high score may generate a letter to a GP recommending “supportive counseling” in a landscape where psychologists have six-month waitlists.

Meaningful change would require integrating mental health care into maternity services, increasing the specialized workforce, and improving public understanding that perinatal mental illness is common and treatable, not a character flaw.
