Mayo by-election candidate Rebekha Sharkie has called for an inquiry on the use of data mining software to target voters.

Sharkie’s comments come in the wake of comments from opponent Georgina Downer on the resettling of asylum seekers in New Zealand, a recently hot topic with only two weeks until the by-election.

The i360 information sourcing program used by the Liberal party in their Mayo campaign is an area of concern, being used to target voters in key seats, according to Sharkie.
