A council manager, Richard McWha, says the biggest issue facing the trust and the council is the long-term financial sustainability of the centre.
Committee member Christine Fletcher said she was very proud of the facility and looked forward to a sustainable business model.
Mrs Fletcher could not understand how the council could be so "pig headed"about keeping the phoenix palm.
She said the parks, community and lifestyle budget -- which the Pah Homestead falls under -- was faced with a proposed 40 per cent capital spending cut in the new 10-year budget.
The committee requested officers to explore options that excluded general admission charges for a more sustainable model in the medium term.
The committee also heard from James Wilson, the chief executive of Q Theatre, who updated councillors on the theatre, which he said had become a magnet for the performing arts since opening in September 2010.
Mr Wilson said the theatre was in a good financial position and benefiting from an innovative and buzzing performing arts sector.
The flexible arts venue cost $21 million to build, including $9.6 million from ratepayers. In the past year it hosted 538 individual public performances.
The committee went behind closed doors to hear about commercial opportunities, including new venue charges, for the theatre.
