A sinkhole roughly 8–10 m wide and several metres deep has opened on the AJ Burkitt Reserve sporting oval in Heidelberg, directly adjacent to the North East Link tunnel alignment in Melbourne’s northeast. Victorian Infrastructure Delivery Authority has confirmed the “surface hole” is in the vicinity of active tunnelling operations, leading to a work pause while engineers and emergency crews carry out geotechnical investigations and monitoring. No injuries or structural damage have been reported, but the area remains fully cordoned off pending cause determination and stability assessment.

A disused UK carbon dioxide production plant has been recommissioned by the government to address a CO2 shortage triggered by the Iran conflict, with officials calling the gas “vital” for safe nuclear power station operation. CO2 is required for reactor systems such as coolant circuits, pressurisation and fire suppression, making supply-chain resilience a direct nuclear safety and availability issue. Engineers should expect renewed scrutiny of single-point vulnerabilities in industrial gas logistics and potential retrofits to diversify on-site CO2 storage and backup supply routes.

Pilbara Ports handled 63.7Mt of cargo in March 2026, an 8 per cent drop year-on-year after Cyclone Narelle forced temporary closures at Port Hedland, Dampier and Ashburton. Iron ore exports from Port Hedland, which typically exceed 50Mt per month, were most affected as shipping channels and berths underwent post-cyclone inspections and staggered re-openings under marine safety protocols. The disruption highlights the need for cyclone-resilient berth structures, dredged channel management and robust stockyard capacity planning across Pilbara export supply chains.
