The Labor Party has crowdfunded thousands of dollars to run a TV ad created by the five-year-old daughter of senator Sam Dastyari, called "The Least Negative Ad Ever".
Labor is doing a last minute TV ad blitz, before the political advertising ban comes into effect at midnight on Wednesday.
Analysis from advertising monitoring firm Ebiquity has found that although the Liberal party is outspending the other parties on overall ad buy, Labor is running proportionally more negative ads.
Labor leader Bill Shorten wouldn't comment on the negative ads, instead saying he loved the TV ad created by the "two stars of this election campaign" - Hannah and Charlotte.
