Property Council Hunter and Central Coast Regional Director Nuatali Nelmes said the rezoning proposal was a strong vote of confidence in Gosford's future as a growing regional city.
"This is a really positive step for the Central Coast - it clears the way for more homes, more activity, and more confidence for local investors and builders," Ms Nelmes said.
"Gosford is perfectly positioned to thrive as a true university town, with the University of Newcastle's new campus and the potential to redevelop the former TAFE site anchoring new opportunities for education, housing and innovation," she said.
Ms Nelmes said the next priority must be investment in local infrastructure to keep pace with growth.
"To make this vision work, we need to see funding for enabling infrastructure - especially the Etna Street Bridge - which is critical to connecting new housing, the hospital with the city centre and rail station," she said.
"The Central Coast is expected to experience significant population growth in the years ahead, with the region tasked to deliver more than 9000 new homes by the end of the decade.
"That means we need sustained investment in serviced, accessible land and the infrastructure that makes new communities possible."
Ms Nelmes said Gosford's revitalisation was a test case for how government and industry can work together to deliver well-located housing in regional cities.
"Gosford's planning controls already provide a strong foundation for investment, and with the right infrastructure in place, the city can lead the way in delivering the next generation of housing and jobs for the Coast," she said.
"Gosford's revitalisation is about more than rezoning land. It's about creating a connected, liveable city that attracts students, families and new businesses, while supporting the people who already call the Coast home," Ms Nelmes said.
