An analysis of just four Centrelink payments, the Parenting Payment, the Carer Allowance, the Disability Support Pension and the Bereavement Allowance, revealed that in 2008, more than 168,000 Australians missed out on government assistance estimated to be worth $623.8 million. Research shows that people are excluded because of: a lack of awareness about available assistance; the complexity of claim forms and procedures; the stigma perceived to be attached to claiming assistance payments and concession benefits.
