Electric vehicle maker BYD removed any reference to "China" and "surveillance" from its Australian privacy policy, just days after questions from Four Corners.
The policy named China as one of 16 countries where the data of Australians could be sent.
BYD has been selling vehicles here since 2022.
When Four Corners asked about its privacy policy, BYD replied two days later saying it had "undergone a review and been updated".
All references to China were gone, along with any mention of surveillance.
The new policy was uploaded to BYD's Australian website just an hour and sixteen minutes before the company sent it to Four Corners.
Confusingly, the website said its new policy no longer applied to vehicles and directed users to a separate document on its app.
While all references to China have been removed, there is nothing to stop it transferring data overseas, including to China.
The Australian Privacy Act allows for data to be transferred to China.
BYD said Chinese authorities had no access to the data of Australians.
BYD's new policy begins with the company saying it values and "respect our customer's privacy".
Ms Kemp said she could not remember reading a connected car privacy policy that "consistently meets requirements of fairness and reasonableness".
In April, Australia's privacy watchdog confirmed it was investigating Toyota and Hyundai over whether they were managing customer data from connected vehicles in accordance with the law.
Last month the government released draft legislation to update Australia's Privacy Act, acknowledging the risks posed by emerging technologies, including connected vehicles.
Ms Kemp said an overhaul of the Privacy Act was much needed.
