She is the only witness listed for the day, suggesting she may face an intense session of questions.
The former Labor leader is expected to be grilled over a slush fund operated by her former boyfriend Bruce Wilson when he was an official with the Australian Workers' Union in the early 1990s.
Ms Gillard was a lawyer with the firm Slater and Gordon at the time and did work advising the union, including advising on the setting up of the fund.
Witnesses at the commission have testified Mr Wilson gave Ms Gillard money from the slush fund to pay for renovations to her house. Ms Gillard has repeatedly denied the claims.
Ms Gillard's former boss at Slater and Gordon, Judge Bernard Murphy, will be called as a witness on Tuesday.

This is another legal farce, that alleges that Gillard will be 'grilled'.
Julia Gillard sat in office fraudulently, and should have been removed immediately, and trialed for treason - no lawyers are allowed to take office.
The so called 'authorities' supported her criminal reign in office.
Similarly, watch the Anglo-Masonic brotherhood step in where nothing happens to Gillard.
This is another clear 'money for mates' scam.
