With construction starting in the new year, a 1,400-metre "megazip" zipline is to be built in Mount Coot-tha, in Brisbane's west. The zipline will start at the Mount Coot-tha summit and follow through to the JC Slaughter Falls picnic area. Patrons will be shuttled between the bottom of the ride back to the top. There will be 6 parallel lines so adventurers can enjoy the views of Brisbane’s skyline while riding at speeds of up to 65 kilometres per hour, side-by-side with other enthusiasts. The cost per ride has yet to be determined. The project is to be built by Brisbane-based company Zipline Australia. 

The project would be the longest and highest vertical drop in the country, using technology previously unseen in Australia, according to Zipline Australia spokesman Matthew Thompson, who said: "This really takes it to another level."

Brisbane Lord Mayor Graham Quirk said the Brisbane City Council would put $1 million towards the project, which will also be funded through the private sector.

"The company will also construct the longest pedestrian suspended bridge walk in the Southern Hemisphere, a 300-metre walk through the treetops above JC Slaughter Falls," Cr Quirk said.

The project was promised by the Lord Mayor before his re-election in 2016, even though he’s not committing to trying out the new attraction. "I'm not a heights person — that's when the power of delegation comes into play," he said.

The council promised the surrounding environment would be treated "sensitively," so there was no need for an environmental impact assessment.
