The commission launched Federal Court proceedings against Ms Asmar in August, alleging she falsely claimed more than $120,000 as relevant business expenses.
It's also claimed she authorised more than $2.7 million to be paid to a printing business that invoiced for products and services that were never received.
At the first court hearing on September 3, Ms Asmar's barrister Yasser Bakri flagged he would be making an application to stay the civil case.
He said the application was necessary because it was "reasonably possible" his client would face criminal charges for the same alleged offending.
Ms Asmar's lawyers filed the interlocutory application with the court on September 12.
Justice Craig Dowling on Tuesday set out dates for the parties to make submissions either in favour or against the stay application.
Ms Asmar will have to put forward her case by October 15 while the commission has until October 29 to respond.
The application will be heard in the Federal Court on November 22.
Ms Asmar's husband David, Health Services Union branch president Rhonda Barclay and union officials Kerry Georgiev, Nick Katsis, David Eden and Lee Atkinson, are also listed as respondents to the commission's civil case.
It's alleged the senior officers at the health union's Victorian branch approved payments or allowed their unique personal banking tokens to be used by the branch's finance manager to make payments.
The alleged conduct occurred between 2016 and 2021.
