A group of environmental organisations is challenging a decision by the Electoral Commission that would require their Climate Voter initiative to be registered as a third-party election promoter.
The commission has advised the group its campaign and website, which call on voters to decide based on parties' climate-change policies, are election advertisements.
Under the Electoral Act, any body that spends more than $12,300 on election advertising needs to be registered with the commission.
Steve Abel from Greenpeace said the group disagreed with the commission's advice it was a third-party promoter, and was taking its case to the High Court.
