The Australian Greens have expressed regret at the government's decision to delay implementing seriously overdue changes to the early education and care sector for another year.

"Early education and care clearly isn't a priority for the Turnbull government," the Greens' early education and care spokesperson, Senator Sarah Hanson-Young said.

"The Liberal Party promised, before the last election, to tackle the rising cost of childcare.

The government's childcare package will result in hundreds of thousands of families being worse off and will need to be amended, the Australian Greens have said.

"This package doesn't do what the government said it would and will, instead, leave hundreds of thousands of families worse off," the Greens' early childhood education and care spokesperson, Senator Sarah Hanson-Young, said.

"Far from helping new mothers re-enter the workforce, the government's strict activity test will make it harder for casual workers and those with irregular hours to access care.

The Australian Greens will refer the Coalition's recently announced childcare package to a Senate inquiry amid growing concerns that many families will be left significantly worse off by the changes.

"I'm very concerned that some families will be worse off and some children will be left without access to any early education at all," the Greens' early education and care spokesperson, Senator Sarah Hanson-Young said.

South Australian Greens Senator Sarah Hanson-Young has written to the Flinders University Council and Chancellor urging them to follow the University of Western Australia and reject the Abbott government’s desperate bid to find a host for climate sceptic Bjorn Lomborg.

"Flinders University should reject the Abbott Governments bribery of research money in exchange for hosting the climate sceptic Bjorn Lomborg," South Australian Greens Senator Sarah Hanson-Young said today.

“Investment in early learning is crucial for our kids but it can’t be delivered off the backs of poorer families and new mothers,” Australian Greens spokesperson for Early Childhood Education and Care, Senator Sarah Hanson-Young said.

"The Abbott Government has shown its true colours when it comes to supporting working mothers by cutting Paid Parental Leave and locking half of all new mothers out of accessing the scheme - robbing new families of $11,500 each. 

Quality education and care must be assured for parents looking for in home care for their children, the Australian Greens have said today.

"Minister Morrison’s nannies pilot program quite simply looks like a rebadging of the In Home Care program”, Greens spokesperson for Early Childhood Education and Care, Senator Hanson-Young said.

“The Minister needs to confirm whether this is new money or if it is being taken from the existing In Home Care program.

Tony Abbott's childcare announcement contained no detail and lacked any commitment to increased funding that the sector desperately needs, the Australian Greens have said.

"Childcare funding must be increased to ease the impact of soaring fees," the Greens' early education and care spokesperson, Senator Sarah Hanson-Young said.

“Fred Nile's comments are naive and misinformed. He is completely out of touch with the needs of modern day parents”, Greens’ spokesperson for early childhood education and care, Senator Sarah Hanson-Young said.

“Comparing childcare to orphanages is absurd and an insult to both women and men around the country.

“It's time for selective moralisers like Mr Nile to lay off the ‘parent guilt’”.

The Australian Greens have called on the Abbott government to release the Productivity Commission's childcare report immediately.

"The childcare sector is in crisis and the government must release this report immediately," the Greens' childcare spokesperson, Senator Sarah Hanson-Young said.

"What the draft report showed us is that, if the government doesn't increase funding, the childcare crisis will continue to worsen. Tinkering at the edges won't do anything until overall childcare funding is increased.

An overwhelming 86% of Australian parents say that fees are one of their biggest concerns when it comes to getting their children into regular childcare, an Australian Greens poll of over 1000 parents has found.

"Parents from around the country are struggling under the weight of increasing childcare fees and it's time the government acted," the Greens' childcare spokesperson, Senator Sarah Hanson-Young said.
