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.

Completion of the highest activity radioactive waste management programme at the Trawsfynydd nuclear power station in north Wales marks a key decommissioning milestone after roughly 20 years of work. High‑risk materials from the Magnox-era site have now been retrieved, conditioned and placed into shielded intermediate-level waste stores designed for long-term containment and future transfer to a geological disposal facility. The shift away from active waste handling allows decommissioning teams to focus on structural dismantling, civil works on reactor buildings and progressive reduction of radiological hazards on site.

CIRIA has issued a Good practice guide for managing climate change and extreme weather in land development, the first UK guidance to directly link projected climate impacts with physical changes in geotechnical and geoenvironmental conditions across the full project life cycle. Trigger events cited include the 2022 heatwave, which generated 23,000 subsidence claims and an estimated £219m payout by ABI members, and Storm Babet’s 2023 bridge collapses. The two-part guide combines current climate–geo risk knowledge with a practical framework, diagrams, tools, and case studies to structure consistent assessment of shrink–swell, flooding, groundwater shifts, and landslides.
