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.
