An "act of grace" compensation claim, on behalf of affected Trio Capital investors, is set to be filed by April after a lobby group resolved to continue its work on the ground-breaking bid.
Nearly 200 people attended a public meeting on Saturday, held by the group, which is representing Wollongong investors who were denied access to a $55 million compensation package after the Trio Capital collapse.
Victims of Financial Fraud secretary John Telford said attendees had resolved to continue working on the "act of grace" compensation claim and hoped to file it by April.
He said the document, to be submitted in Canberra, aimed to outline why members deserved the claim.
"We want to justify why we've taken this course of action and explain we've been given no recourse by the government," he said.
"It's an enormous amount of work and it's been frustrating trying to get documents, but we're sticking with it."
The claim, which Mr Telford believes is the largest of its type in Australian history, has been compiled on behalf of 300 investors.
The group was denied access to compensation in 2011 because they were not in government-regulated superannuation funds.
They had hoped a year-long parliamentary inquiry would recommend an extension of the compensation arrangements.
But they were left disappointed after MPs found it was "not prudent at this time" to protect self-managed super fund investment from fraud and theft losses.
Mr Telford said the group had been buoyed by statements of support from Member for Wollongong Noreen Hay and Wollongong City councillor Vicki Curran.
Despite their encouragement, Mr Telford said the group had resolved to condemn Federal MPs Stephen Jones and Sharon Bird for failing to attend the meeting.
The group also called for Wollongong Against Corruption member Paul Matters to stand in the federal election and put pressure on the Throsby seat.
At the meeting, University of Sydney professor Dr Evan Jones detailed alleged corruption within the banking and financial sectors and the lack of policing from bodies like the Australian Securities and Investment Commission.
