Electoral law changes clear lower house

The federal government has agreed to put on hold its push to make impersonating a commonwealth agency or service a criminal offence.

The measure was part of a suite of changes to electoral laws aimed at stamping out campaigns like Labor's so-called 'Mediscare' during the 2016 election.

But cabinet minister Steve Ciobo on Wednesday removed it from the package and told parliament separate legislation will "deal with this issue in the future".

The remaining proposed changes cleared the lower house with Labor's support.

They include the requirement for people behind political messages - whether sent by text, email, phone or online - to identify themselves and the ability of the Australian Electoral Commission to seek fines of up to $126,000 for breaches of electoral laws.

Mr Ciobo noted the laws won't come into effect until six months after the bill receives royal assent.

"Therefore, it will not affect the Australian marriage law postal survey," he said.
