A greens-led protest against the proposed Mt Coot-tha zipline project approved by Brisbane City Council saw about 150 people march outside City Hall this morning.

The protest, organised by Greens MP for Maiwar Michael Berkman after the council announced the approval of the controversial zipline project late Friday, was also attended by Labor and independent councillors as well as community groups and passers-by.

Dr Lynham said the final decision on whether the state would approve the controversial project rested with his department. More than 3200 public submissions were against it.
