A gate has been added to the fence of a Como West playground near where a boy, 8, was hit by a car earlier this month.
Sutherland Shire Council says the move followed requests from local residents and park users "earlier this year".
Police said the car was travelling at low speed when it hit the child in Wolger Street, near Henry Lawson Reserve, on July 7.
The boy was treated at the scene before being taken to the Sydney Children's Hospital in a stable condition for treatment of head injuries.
The driver, a man aged 18, underwent mandatory tests. Police have not advised of any charges being laid.
"Sutherland Shire Council recently installed a gate to complement the existing fencing at the entrance to Henry Lawson Reserve playground at Como in response to requests received earlier this year from local residents and park users," a spokeswoman said after a resident advised the Leader of the addition.
"Council values the feedback received from local residents in advocating for enhancements to our parks and open spaces - including the installation of additional safety measures - to ensure these spaces can be enjoyed safely by all members of our community, including those with young children and other vulnerable user groups."
The council completed an upgrade of the playground in Henry Lawson Reserve in May 2020.
