The appointment was criticised by Australian Greens leader Christine Milne who claimed Morrison had a lack of compassion. With a softened change in image, Morrison was commended by welfare and community groups for his accommodating approach and eagerness for the portfolio. Morrison encouraged working mothers and endorsed fixes to the childcare system by making indexation changes to the Family Tax Benefits payment.
