Teals Allegra Spender and Zali Steggall form new political party | ABC NEWS

Independents Allegra Spender and Zali Steggall have confirmed plans to form a new political party.

But they're yet to convince any of their crossbench colleagues to join what they call their "responsible alternative" to the major parties.

There's long been speculation about a formal grouping of the so-called Teal independents, who've won previously safe Liberal seats over the past three elections and received some funding and campaign support from political organisation Climate 200.

The pair had confirmed they were holding talks about a party in recent weeks.

Today they revealed it'll be called Community Strong Australia, but it's yet to be formally registered and has no leaders or candidates.

Party members will "collaborate" on policies, the pair say, but will retain a free vote, a model they say is "not about choosing between independents and parties but combining the strengths of both".

The pair also confirmed that Climate 200 wasn't directly involved, with Ms Steggall saying the funding group would "remain focused on independent representation".

Climate 200's ability to donate to independents across the country stands to be significantly curtailed by new electoral funding laws passed in the last parliament, which Ms Steggall and Ms Spender have both suggested are biased towards political parties.

A political party will have greater flexibility to prioritise resources and support multiple candidates than a collection of like-minded independents working together without a party structure.
