Shark-spotting drones will monitor beaches from dawn to dusk after a savage attack on a young mother.
Leah Stewart had her arm amputated after being bitten by a great white shark while swimming at Coogee Beach in Sydney's east on June 13.
The 34-year-old mother of a toddler spent a week on life support and endured multiple surgeries and has a long journey ahead of her, but is now off the critical list.
Ms Stewart was swimming between the flags when she was attacked.
NSW Premier Chris Minns has announced his government will invest an extra $34 million in a major scale-up of drone coverage across beaches in Sydney and along the state's coast.
Under the expanded program, around 70 beaches will benefit from drone monitoring 365 days of the year, including at least one beach in every coastal local government area.
This additional monitoring by Surf Life Saving NSW will prioritise beaches with high numbers of swimmers, surfers and paddlers including in Sydney and the North Coast, where shark incidents have become more frequent.
This expanded monitoring will start on Wednesday and include year-round coverage across all Sydney beaches expanding from 26 to 38 beaches - from Palm Beach to Cronulla.
"We know people love getting out to our beaches and they should feel confident doing it," Mr Minns said on Sunday.
"While no one can ever promise no shark interactions, this investment is about putting more eyes in the sky so we can spot sharks earlier and give people a clear heads-up when they're in the water."
A fundraiser page set up to fund Ms Stewart's medical procedures and help her family has garnered more than $500,000.
Surf Live Saving NSW will continue to lead drone operations and will scale up their use during busier seasons.
Ms Stewart's attack reignited calls to cull shark populations to protect swimmers, but Mr Minns has said the great white shark population can't be targeted as it is protected.
Shark nets, which are removed during the winter whale migration season, will be reinstalled in September.
