Parents will soon be able to share in up to six months of paid parental leave as part of an expanded scheme.
New laws being introduced to parliament on Thursday will allow for families to be able to access 26 weeks of paid parental leave by 2026.
Families already have access to 20 weeks of paid leave, but under the changes, that amount will increase by two weeks each year from July 2024, until the 26-week rate is reached in 2026.
While the 26 weeks will be able to be shared by both parents, the changes will see each parent receive four weeks of reserved leave as part of it.
Both parents could also use the four weeks of reserved leave at the same time.
Women's Minister Katy Gallagher said the changes were designed to allow for flexibility in care arrangements.
"We know that good women's policy is also good economic policy, and this investment will promote parenting as an equal partnership while boosting the economy," Senator Gallagher said.
"This is all about making sure that every family has more choice and better support."
The expansion to paid parental leave to six months was first flagged in last year's federal budget.
The expanded scheme is earmarked to cost $1.2 billion between 2022/23 and 2026/27.
It's estimated the changes to the paid parental leave scheme will benefit more than 180,000 families each year.
Of the almost 179,000 people on paid parental leave in the 2021/22 financial year, 99 per cent were women.
Social Services Minister Amanda Rishworth said the changes followed advice received from the government from the Women's Economic Equality Taskforce.
"The roughly 180,000 families who receive paid parental leave each year will benefit from a more generous scheme that supports maternal health and wellbeing, encourages dads and partners to take leave, and gives families flexibility to choose how they share care," she said.
"These changes will provide better security and choice for families, they strike the right balance between supporting our working families, encouraging greater gender equality and supporting greater workforce participation."
