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 23-year-old grounds worker, Kamil Grygieniec, was killed when a ride-on mower without its roll-over protection system (ROPS) descended a steep slope and overturned into a village pond at North Stainley, near Ripon, on 8 October 2021. HSE investigators found the factory-fitted ROPS had been removed and that no suitable, site-specific risk assessment for mowing on sloping, uneven ground had been carried out. Employer MHS Countryside Management Limited, of Bishop Auckland, was fined £27,000 plus £11,166 costs at York Magistrates’ Court for breaching Section 2(1) of the Health and Safety at Work etc. Act 1974.

Multiple sinkholes along Summit Avenue near Lewis Street in Phillipsburg, New Jersey have triggered a local state of emergency after one collapse swallowed a loaded dump truck and undermined adjacent properties. Authorities have evacuated several homes, closed the affected road section, and are investigating suspected subsurface voids linked to ageing water or sewer infrastructure beneath the asphalt pavement. Geotechnical teams now face urgent stability assessment, utility leak detection, and staged backfilling or grouting in a constrained urban corridor with active buried services.
