Committee chairman Vic Arcus said the board's decision would give the group more time in which to produce a comprehensive feasability study.
He said it would mean they group could consult more widely, produce an indepth financial business case and possibly expand on the architectural concept drawings of the project.
"It will certainly allow us to present a much more full proposal."
The Fairfield Project will immediately put in applications to some philanthropic trusts to raise the funds needed to pay for the feasability study. Mr Arcus estimated the six-month study would cost $15,000-$20,000.
"The study may also involve more design aspects. We've been really pressed for time so this means we can expand the proposal in more detail, talk more fully with all stakeholders."
He said it would also mean they could have discussions with funding sources to gauge the level of support there may be for the project.
Mr Arcus said the committee had been inundated with supportive letters and emails and messages on the group's Facebook page.
