Independent councillor Vicki Curran will ask Wollongong City Council to beef up its objections to the proposed Port Kembla expansion by requesting a halt to all expansion activities until adequate transport infrastructure is in place.
Cr Curran will raise a notice of motion at Monday night's meeting asking the council to write to Premier Mike Baird and two senior ministers, asking them to put all assessments of Port Kembla's outer harbour on hold until a formal infrastructure plan has been made.
She also wants to ask the government to commit to providing all infrastructure such as rail upgrades before further expansion of the port.
"I'm concerned there will be thousands more trucks on our already congested road network if the government doesn't put an infrastructure plan in place immediately," Cr Curran said, adding that she had no confidence in the government's claim that the expansion would not put more trucks on the roads.
"Without a set plan outlining where and when we will get infrastructure, the government is jeopardising the future of the port, and the safety and amenity of Wollongong residents."
Cr Curran had previously raised concerns about the port plan, saying the private tenants must pay for improvements to public infrastructure that would be affected by the planned modification.
