The climate group that backed the election of teal independents to federal parliament has called for an overhaul of the country's political donation laws.
Climate 200 convenor Simon Holmes a Court will appear before a parliamentary committee examining this year's federal election as part of the latest round of hearings on Thursday.
The organisation, which lent support to prominent independent candidates at the May election, has proposed reforms including the real-time disclosure of political donations of more than $1000.
In its submission to the parliamentary committee, Climate 200 said current laws had an entrenched advantage afforded to major parties as well as incumbents.
"While Climate 200 strongly believes in reducing the influence of private interests and big money on politics, we have seen how mechanisms such as donation and expenditure caps and advance public funding can have perverse effects on democracy," the submission said.
"A well-functioning democracy should not inhibit new entrants from running for parliament or significantly advantage some candidates over others."
The organisation said while there have been calls for caps on political donations to reduce private interest, such moves would make it harder for those outside major parties.
Climate 200 has also lent its voice to calls for truth in political advertising laws.
The submission said such laws would give greater transparency in the lead-up to an election.
"Every election cycle, advances in photo-editing software and 'deep fake' videos make it possible for more and more realistic lies to be distributed," the submission said.
"There are numerous infamous examples in Australia's federal elections of misinformation and lies in political advertising, which misleads voters and compromises our democratic process."
Labor's national secretary Paul Erickson, who attended the hearing on Thursday, called for a reduction of the donation disclosure threshold from $15,200 to $1000, as well as real-time disclosure.
The party has also offered support to a proposal for a single, national electoral roll as a way of reducing disenfranchisement.
Australian Electoral Commissioner Tom Rogers said having one roll was a "sensitive and complex issue" and the commission had worked closely with state bodies to reduce discrepancies.
He said before a concerted effort was launched there had been a divergence of a "couple of hundred thousand electors" between the federal and state rolls.
"We worked to get that down to a very small number," he said.
After Mr Rogers presented his evidence, the committee hearing was disrupted by a former Queensland minister who hastily took up a chair next to the departing commissioner.
Steve Dickson, who served as a minister in the Newman government and is a former One Nation leader, unsuccessfully ran as an independent candidate for a Senate seat in Queensland at the May election.
Mr Dickson was shut down by committee chair Kate Thwaites, who told him "this is for committee members".
She temporarily suspended the hearing and Mr Dickson was escorted from the room by security.
Just before the hearing, Mr Dickson posted on his Facebook that Thursday marked "the only significant thing left to do to speak up about what happened during the federal election when I ran for a seat in the Senate".
Mr Dickson's written submission to the committee was published on its web page but was heavily redacted for legal reasons.
"I do not accept, that in a Democratic Country, we would allow voters to be misdirected or misled without consequence," he wrote in the submission.
