Free-to-air networks will still show election advertising on television during the so-called blackout period this week by allowing paid political campaigns to be watched through their digital catch-up apps or on smart TVs.

A legally-enforced blackout period will be in place from 12am on Thursday until the polls close on Saturday at 6pm to limit voters from making rash choices based on an advertisement. The rules were also created to curb political parties from making untested claims when there isn't enough time for scrutiny.

But while these rules apply to broadcast media, including the major TV companies and radio licence holders, the law doesn't apply to streaming applications like Seven West Media's 7plus, Nine Entertainment Co's 9Now and Network Ten's 10play.

Free-to-air television sources have confirmed that Seven, Nine and Ten will accept political advertising on their digital platforms up until voting closes on Saturday, with most expecting a spend from all the major parties.
