More than 1,000 vehicles were transported to North Park from Sydney, including two commercial vehicles, on the night of the incident.
The ABC has learned the transport services are working closely with Transport for NSW, which operates the North Park ferry terminal.
It is understood the North West Freight Services facility was one of the two major ports in the CBD at the time.
“We are working with Transport [for NSW] to try and get a better understanding of what happened,” Mr Kelly said.
Mr Kelly is urging residents to take extra precautions. “
That will allow us to take any action that we deem necessary to minimise the risk to people.”
Mr Kelly is urging residents to take extra precautions.
“In the next 48 hours we will be making a recommendation to the public that there is a greater risk to the health of their children,” he said.
Mr Kelly also warned residents to not allow their children to ride the ferry as a precaution.
“This is a very, very dangerous situation,” he told the ABC.
“If you don’t know where to go, or you don.
There’s a lot of things you need to be aware of.”
The North Park Transport Services website said a total of 1,200 vehicles were used in the ferry service.
