Labor has signalled a fresh pursuit of Gladys Liu after it emerged the Liberal MP helped a Chinese-owned company secure access to federal politicians.
Opposition Leader Anthony Albanese renewed calls for Ms Liu to explain herself in federal parliament.
"We need to be diligent about ensuring that the parliament looks after these issues," he told reporters in Canberra on Wednesday.
"Every day there's issues that seemed to be raised about the member for Chisholm and the government won't let Gladys Liu make a statement to parliament."
Ms Liu has for months faced questions about her links to Chinese organisations.
It has now emerged she helped a company endorsed by the Chinese Communist Party win government support for its venture.
The company made a big donation to the Liberal Party to win access to federal politicians, the Nine newspapers report.
Months later, Australian Federal Police investigated suspicions the company was funded by laundered drug money.
Responding to the reports, Mr Albanese also made reference to photographs of Ms Liu with a man who was allegedly approached by Chinese intelligence agents to run for federal parliament.
"I think there is real concern about a lack of accountability," he said.
"How is that Gladys Liu says that she didn't know the gentleman who's photographed sitting next to her in her house?"
Independent senator Jacqui Lambie said both major parties lacked the courage to confront foreign interference.
Senator Lambie said Australia was a "sitting duck" as China tried to reshape its democracy.
"Where's your courage, what are you scared of? This is not some whacky conspiracy theory. This is happening," she told parliament on Tuesday night.
