The opposition's social services spokeswoman, Jenny Macklin, has released a statement about the government's linking its childcare package to the national disability insurance scheme.

"This is a disgraceful political game of brinksmanship," Ms Macklin said.

"People with disability do not deserve to be treated with such contempt by the Turnbull Government."

"The NDIS is a bipartisan reform that should be above politics. Instead, Mr Turnbull wants to use the NDIS as a bargaining chip in negotiations with the Senate."
