Aaron Finch claimed a rock was thrown at Australia's team bus and smashed a window following their Twenty20 international victory over India on Tuesday.
Australia were making their way back to their hotel after an eight-wicket victory at the Barsapara Cricket Stadium in Guwahati when Finch says the incident occurred.
The opener tweeted a photo of a broken window from inside the vehicle with the caption: "Pretty scary having a rock thrown through the team bus window on the way back to the hotel!!"
Australia were involved in a similar incident after the second Test against Bangladesh in Chittagong last month and were given stiffer security as a result.
The final match in the T20I series against India – which stands at 1-1 – will take place in Hyderabad on Friday.
