Former Greens senator Larissa Waters could be set for a political comeback after receiving the overwhelming support of the party to retake her Senate position.

It comes less than nine months after she resigned during the federal citizenship crisis, following her discovery that she was a dual Canadian citizen.

A month-long poll by the Queensland Greens was counted at the end of last week, delivering Ms Waters with 75 per cent of the primary vote from members, securing her place as the lead Senate candidate.

It means she could take back her former position that was filled by Andrew Bartlett when Ms Waters resigned last July.

Last month, Senator Bartlett was pre-selected for the federal seat of Brisbane but had not indicated yet if he would wait until the federal election was called before stepping aside.

Ms Waters said she was eager for a comeback.

“Politics hasn’t improved and it’s clear to me why people are so fed up with the big parties,” Ms Waters said.

“Labor and the LNP protect the interests of their corporate donors instead of the people they were elected to represent.”

Senator Bartlett said he welcomed Ms Waters’ return to the top of the Greens Senate ticket.

“We had a breakthrough victory in the Brisbane City Council in 2016 and an even bigger breakthrough getting someone into the Queensland Parliament in 2017,” Senator Bartlett said.

“Brisbane’s our strongest seat and we’re wanting to give it a strong shake in terms of taking that seat off the Liberals if we’re really going to dramatically change the direction of politics in this country.

“The key priority for myself and all the Greens in Queensland is to retain our Senate seat and that’s the key reason why I chose to run for a Lower House seat rather than just step out of things altogether, because we build on that momentum.”
