The investigation unit known as Strike Force Nuralda has asked betting agencies to reveal every gambling transaction on every market for Sea Eagles games in 2015 and 2016, according to News Corp Australia report.
The news comes as Sea Eagles chairman Scott Penn claimed Manly was a victim of "guilt by innuendo", revealing the club had yet to be contacted by police.
"We are concerned about the way in which the club brand has been tarnished by speculation," Penn said.
"It is guilt by innuendo."
