A parcel of once-contaminated land in North Wollongong is set to move on from its former life as a petrol station and be developed as a bouldering gym - the second one on that street. The 3500sq m site at 122-126 Montague St was formerly a Mobil service station with nine massive underground fuel storage tanks which have since been removed. A development application (DA) is on exhibition at Wollongong City Council from a Sydney-based company called Global Vertex Group Pty Ltd, which lists as its sole director a 28-year-old named Ke Zhang. Bouldering is similar to indoor rock climbing - except the participants do not have any ropes attaching to them. They climb free - and fall free, onto large padded pats.

It would employ two staff. A report from an environmental consultant was included and attested to the fact that the land had been appropriately rehabilitated. "It is considered that the subject site is adequately remediated and can be utilized for the purpose of a bouldering gym," the report from Golder Associates said. "Further, it is noted that the proposal does not seek significant excavation or disturbance of soil." The fuel infrastructure had been removed, and soil and groundwater "impacts" were contained, so did not pose a threat of spreading, or endangering workers. "Residual groundwater impacts identified on-site are ... present at concentrations below the human health assessment criteria and therefore do not represent an unacceptable risk to offsite human health receptors," the report said. The NSW Environment Protection Authority (EPA) had reviewed the information submitted to it and determined that regulation of the site under the Contaminated Lands Management Act was not required.
