Disability advocates fear that information about the National Disability Insurance Scheme will not reach thousands of potential participants after the federal government dumped its ad campaign six weeks before the introduction of the $22 billion reform.

The government scrapped the $14 million advertising campaign as part of a $66.7 million federal budget measure, diverting the money to the NDIS savings fund, which will contribute to the future costs of the scheme.

Under a confidential settlement, Ms Jones now expects to receive the full value of her total and permanent disability insurance (TPD) payout.

The National Disability Insurance Agency, which administers the scheme, is already promoting it through the social media hashtag #ndisready and community meetings in areas where the scheme is being launched.

Advocacy director of the NSW Council for Intellectual Disability Aine Healy said some people with a disability and their carers do not use social media and those who do are likely to already be informed about the NDIS.
