For the first time, a stand-alone age discrimination commissioner will be able to advocate for the rights of older Australians in the community and workplace and handle complaints under the Age Discrimination Act.

"A dedicated commissioner would tackle discrimination in getting a job, applying for a promotion, enrolling at TAFE or university, applying to rent a house or using services such as banking, superannuation, insurance and government services," McClelland said.

Until now, the sex discrimination commissioner Elizabeth Broderick has been responsible for age discrimination issues.

The bill also includes important amendments to improve the Sex Discrimination Act including stronger protections from sexual harassment and discrimination on the basis of family responsibilities and breastfeeding.

The new commissioner will take office from 1 July 2011.
