COTA: Housing prices push pensioners north out of Sydney

AGED rights group COTA NSW has warned both sides of politics their failure to remedy the state's lack of affordable housing supply had created a generation of "reluctant sea- and tree-changers".

COTA NSW chief Ian Day said thousands of pensioners were being pushed out of Sydney to areas like the North Coast.

"We surveyed thousands of people aged 50-plus about housing last year, and were alarmed to discover how many older people are struggling to keep a roof over their heads," he said.

"We found that almost 33% of those who lived in residential parks were from the North Coast, and almost 16% of those who lived in retirement villages were from the region."

Mr Day commended the Coalition's planned $1 billion incentive fund for affordable housing investment.

"(But) we need to see reform of the state's planning regime so that more affordable housing around transport and service hubs can occur, not just in Sydney, but in major regional towns and centres," he said.
