Labor will increase the childcare rebate by 15 per cent, leaving some families up to $31 per week better off.
Opposition Leader Bill Shorten will be in Melbourne on Sunday to reveal the plan, which also raises the childcare rebate cap from $7500 to $10,000.
Labor says that will mean more than 107,000 families won't hit the cap this financial year.
Mr Shorten says the policy - which starts January 1, 2017 - will be funded by scrapping Liberal Party policies.
"Right now, too many families have their pay packet eaten up by child care," Mr Shorten said.
"Better child care is essential to a growing economy."
The package includes:
- New transparency and accountability standards
- $50 million for improvements in family day care
- Increasing services for indigenous children and remote kids by 15 per cent
- $150 million to develop early education work force.
Mr Shorten will be joined by opposition spokeswoman for early childhood education Kate Ellis in Melbourne to reveal the policy.
In an announcement timed to coincide with World Environment Day, the Turnbull government is pledging cash to protect species at risk of dying out.
