In 2018, more than 20,000 people filed claims for plagiaristic practices.
The figure is expected to rise in 2019, with the government planning to launch an internal investigation.
This year, the federal government has been investigating some 2,000 complaints against the Beale-papers, including some involving the plagiarism of former Prime Minister Kevin Rudd’s book “Dreams from My Father”.
While it is rare for federal government departments to be investigated, the inquiry has led to the resignation of one official.
The Government is also investigating claims that Beale has been “failing” to publish his academic credentials.
“I’m disappointed that the university has not acted more quickly and decisively in this matter,” said Mr Beale.
Mr Beales office declined to comment on the internal investigation but in a statement the university said it “follows the law, respects the integrity of the university, and has been fully transparent about our investigation”.
The inquiry is expected later this year.
