The Federal Government is reviewing the relevance of political advertising blackouts on radio and television on the eve of elections.

Under the current rules, broadcasters are not allowed to run political ads from midnight on the Wednesday before a state or federal election.

In a recent submission to a Senate committee, the free-to-air TV networks, represented by Free TV Australia, said the rules should be scrapped.

"These rules do not apply to other forms of electronic media such as internet or mobile advertising, creating significant regulatory disparity," the submission said.

"These rules are no longer relevant or effective given the shift to a 24-hour news cycle and the popularity of online content services.

"Banning election advertising on TV and radio only is no longer effective in enforcing any real blackout as consumers still have ready access to election advertising [including audio-video advertising] online through popular news sites and apps."

A spokesman for Communications Minister Malcolm Turnbull confirmed the Government would review the rules in line with its deregulation agenda.

"The Government has pursued a strong deregulatory policy agenda and is progressing changes to the way in which regulation is created, implemented and reviewed," the spokesman said.

"The election blackout regulation was made at a time when the only non-print forms of communication were television and radio."
