179 submissions have been submitted to Brisbane City Council on Tuesday about the six new ziplines proposed for Mount Coot-tha.

The council-funded project, spearheaded by urban planners Ethos Urban, opened to submissions on November 26, sparking criticism from some over the pre-Christmas launch and its 14-day submissions limit.

The main objections to the ziplines include potential damage to native flora and fauna, commercialisation of natural bushland, and an influx of bus traffic.
