The seamer has been suspended by Zimbabwe Cricket (ZC) and fined US$1,000, although the board did not offer an explanation of Panyangara's indiscretion.
ZC's decision is thought to stem from Panyangara allegedly sharing a video of Mitchell Johnson bowling to team-mates, warning them to expect short-pitched deliveries similar to the Australian's Ashes demolition of England.
A statement read: "Zimbabwe bowler Tinashe Panyangara has been removed from the national squad camp for the ongoing triangular one-day international (ODI) series involving Australia and South Africa, because of indiscipline.
"The 28-year old Panyangara has also been fined one match fee for his behaviour that the national team disciplinary committee found to be disruptive in the build-up to the first ODI of the triangular series, which Zimbabwe played against Australia on Monday."
Panyangara will now train with his country's A squad as they prepare for a tour of Bangladesh.
Zimbabwe lost the opening game of the series by 198 runs to Australia, who were in turn beaten by South Africa on Wednesday. The hosts' next assignment is against the Proteas on Friday.
