Rural health researcher Helen Haines was chosen by Victoria Cathy McGowan's supporters to succeed the independent federal MP when she retires.
McGowan is expected to announce his future Monday at a press conference in Wodonga.  Nearly 200 volunteers from Voices for Indi choose Haines as their next candidate in a meeting to determine a succession plan in Benalla.
"I want to thank the participants who showed up on a hot day, those who got their hands up to be considered and Voices 4 Indi," said McGowan in a statement on Saturday. "I will now consider the outcome of today's process and make further comments on Monday morning."
McGowan has held Indi's northeastern Victorian headquarters since 2013, when he won a splendid victory against liberal parliamentarian Sophie Mirabella.
The national vice-leader, Bridget McKenzie, has hinted to challenge the seat by moving her office from Bendigo to Wodonga and refusing to rule out a potential passage to the lower house.
Liberals have preselected Steve Martin for Indi, even Labor Eric Kerr will run.
McGowan previously refused to confirm any retirement plan, saying that the outcome of the preselection would help her make a decision about her future.
It was understood any future candidate selected in the process would be strengthened when McGowan decided to retire or if he had lost his job. This would not necessarily be in the 2019 elections.
Haines, a nurse, midwife and public health researcher from Wangaratta, said, "If I gain the support of Indi voters, I will be ready to bring that fight to Canberra.
"We have seen in the last six years in India the enormous difference that makes an independent voice in parliament. Cathy gave incredible results for Indi. But the work has just begun and we can not allow the seat back into the hands of the main parties to be ignored once again. "
More than 200 volunteers from previous McGowan election campaigns selected Haines from an expert group of three candidates, the process put candidates through six hours of questions and deliberations.
The decision was made by consensus of all the 200 participants.
