A new survey conducted by Unisys reveals that 41% of Australians have received online ads about a topic they had recently talked about.
More than 1 in 4 participants also said the virtual assistant on their smart device had asked them for more information, or to repeat themselves, even when they hadn't turned it on.
Ashwin Pal from Unisys says Australians are becoming increasingly concerned about their privacy and how their data is being used.
