Deaths at Bayville, Cliffs and Cliffs amusement parks have been reported in recent weeks.
The coronavirus pandemic has seen deaths at amusement parks and other tourist attractions at record levels.
A total of seven deaths have been confirmed at Bayvillas amusement park in the past two weeks, according to the Australian Department of Health and Human Services.
Three people have died at Cliffs in recent days.
The park has been closed for the duration of the pandemic.
The death toll is the highest in any of the parks in the state.
A number of Bayville residents have contacted the ABC after attending the park on Saturday night and Sunday morning.
They said they heard noises in the park during the night, including someone yelling, “Someone is dead”.
One resident said they could see blood on the ground at the entrance to the park.
A local resident, who did not want to be named, said the park had been closed.
“There was blood everywhere,” he said.
“It’s a sad situation, and people should not go to the parks.”
The department said it would hold a public meeting to discuss the situation.
It said the department had received a number of calls from people who had witnessed the death of someone at the park and would continue to assist them with their inquiries.
“We are aware of the ongoing public health concern and are committed to making every effort to provide the appropriate resources to assist with the ongoing investigation,” a spokesperson said.
The department advised people who saw the deaths or were in close proximity to them to stay away.
The agency said it was asking anyone who had information about the deaths to contact police.
