A greenlight on the Forrestfield-Airport Link
The $1.86 billion METRONET Forrestfield-Airport Link, jointly funded by the federal and WA state governments, is set to deliver a new rail service to the eastern suburbs of Perth – with three new stations at Redcliffe, Airport Central and High Wycombe.
A large degree of progress has been made since mid-2021, with works continuing to prepare the tunnels formed using the impressive tunnel boring machine (TBM) for everyday use having been completed. As reminder of the monumental achievement of building WA’s longest tunnels, the 70-tonne TBM has taken on a new life as a industrial sculpture standing proudly at the entrance to the High Wycombe Station precinct.
More recently, Airport Central and Redcliffe stations have undergone safety testing as part of a tunnel ventilation tests which are critical to gauging the tunnel’s safety in emergency scenarios.
APA Group’s Northern Goldfields Interconnect kicks off construction
Nacap has kicked off construction, on behalf of APA Group, on the approximately 580 km long DN300 Northern Goldfields Interconnect (NGI). Nacap’s crews have begun to mobilise the site and the project is set to build momentum throughout the coming months as activities kick-off across the project.
The Northern Goldfields interconnect project involves the construction of a new buried pipeline, commencing at Ambania approximately 50 km east of Geraldton, connecting into the existing Goldfields Gas Pipeline (GGP), approximately 40 km south of Leinster.
APA Group’s investment in the NGI will help stimulate significant economic development within WA and has the potential to unlock hundreds of millions of dollars of investment in the Goldfields region. The region is rich in gold, potash and battery minerals such as vanadium, nickel and rare earths.
