Almost half of NSW baby boomers have had to face age discrimination, according to an NRMA survey.
The survey was carried out as part of the research into a new website - Living Well Navigator - directed at the over 50s.
Forty per cent of the respondents said they have experienced age discrimination themselves or knew of someone who had.
In addition, 37 per cent of people over 50 have little confidence they would be treated fairly in a job interview.
Peter Khoury from the NRMA said this was concerning, especially given the federal government's plan to push back the retirement age to 70.
Mr Khoury said businesses needed to adjust to the realities that come with the ageing baby boomer population.
"There's a lot of debate about the working age being extended, which means a lot of Australian companies need to be prepared for the fact that their workforce is going to be older than it used to be," Mr Khoury said.
With more than half of the NRMA's membership over the age of 50, the Navigator site aims to provide support for those looking to get back into the workforce.
"The Living Well Navigator site assists older workers by providing information on how to get jobs and volunteering information as well as hosting a jobs board to connect older workers with age-friendly employers," said NRMA local director Michael Tynan.
"The site aims to bust common myths and stereotypes on ageing. Those north of 50 have comprehensive knowledge, are highly skilled, active and make valuable contributions to our society."
The website provides a wide range of information for the over-50s - including work, health, travel and supported and independent living.
