The hard-right Rise Up Australia Party says it is considering a preference deal with suspended independent MP Geoff Shaw ahead of Victoria's election.
The Christian party protested on the steps of state parliament on Wednesday, waving Australian flags, in support of free speech and to oppose multiculturalism.
Pastor Danny Nalliah says his party plans to run lower house candidates in all marginal seats including Frankston, where it is "most likely" considering a preference deal with sitting MP Mr Shaw.
"We're speaking with Geoff right now," he told reporters.
"We're contemplating on which way we should go.
"With our preferences it could be very well that he'll get over the line."
He said his party is also talking to the Liberals and other parties in the lead-up to the November 29 poll.
"Parties which support our values, we will support them in preferences," he said.
"We will almost surely be instrumental in getting the next government in by doing preference deals with particular parties to make sure in the marginal seats that they get through.
"We'll lock up deals in the next few months."
Mr Nalliah, whose party wants to ban the Islamic face veil, has been critical of former prime minister Julia Gillard for living in sin and also suggested the Black Saturday fires were caused by weakened abortion laws.
He says politicians seem keener on placating minority groups ahead of the majority.
"The important thing is for people to understand if you come to Australia, you become Australian, embrace the country you've come into, integrate into the Australian culture and way of life and don't try to change this country to where you've come from," he said.
Mr Shaw, a Liberal-turned-independent, is serving a suspension over misuse of his parliamentary car and fuel card.
The margin for Frankston is 0.4 per cent after a boundary redistribution, according to ABC election analyst Antony Green, whereas the Liberals' hold was at 2.07 per cent after the 2010 election.
