TPG Telecom activated three standalone 5G cells covering Kalgoorlie’s central business district on Tuesday, targeting BHP Nickel West roster workers and Kalgoorlie Health Campus staff who reported fixed-wireless congestion during the September school holidays.
The sites use TPG’s 3.5 GHz spectrum holdings and backhaul over a newly lit fibre spur from Coolgardie. Network engineering general manager Brendan Walsh said the deployment was fast-tracked after liaison with the City of Kalgoorlie-Boulder and the WA Department of Health, which needed reliable uplinks for telehealth carts at the regional hospital.
Coverage and speeds
Drive tests conducted by the carrier showed median download speeds above 240 megabits per second along Hannan Street and at the Kalgoorlie-Boulder Airport approach road, with upload speeds near 45 Mbps. Walsh said the cells are configured for network slicing on a trial basis so Nickel West camp operators can segregate operational traffic from public smartphone use during shift changes.
Standalone 5G differs from earlier non-standalone rollouts because the radio access network anchors directly to a 5G core, reducing latency for voice-over-new-radio calls. TPG customers with compatible handsets will see a 5G icon without relying on LTE control channels; older devices fall back to 4G on 700 MHz carriers already in market.
Why Kalgoorlie now
BHP’s Nickel West operations near Kambalda and Leinster depend on fly-in, fly-out rosters housed in Kalgoorlie during turnaround weeks. Union safety delegates raised connectivity gaps after a July storm damaged microwave backhaul on a private mine network, forcing supervisors to drive into town for SIM hotspots. TPG declined to disclose commercial terms with BHP but said enterprise customers can order fixed-wireless access routers with static IP addressing for SCADA backups.
Competitor Telstra already markets 5G in parts of the Goldfields; Optus has limited mmWave trials in Perth. TPG’s push is part of a regional standalone program announced in May, which included Geraldton and Mount Isa upgrades.
Regulatory and community notes
The Australian Communications and Media Authority recorded the facilities under low-impact rules after council consultation. Local retailers along Hannan Street said improved mobile data could reduce reliance on satellite internet kits that became popular during COVID-19 border closures.
TPG will add a fourth cell near the Super Pit viewing area in November if traffic models confirm weekend tourism demand. Walsh said the carrier is also negotiating roaming for emergency services handhelds used by WA Police Goldfields officers.
