Authorities issued urgent evacuation orders for hundreds of residents in high-risk areas as soaring temperatures, dry vegetation and strong winds combined to create dangerous fire conditions. Emergency services said fires could spread rapidly and urged residents to follow official advice without delay.

The Bureau of Meteorology forecast temperatures in Melbourne to exceed 43 degrees Celsius, marking the city’s most extreme heat since 2009. Officials warned that infrastructure, power supplies and public transport could be strained under the intense conditions, while health authorities cautioned vulnerable populations to remain indoors and hydrated.

Australia has faced increasingly frequent and severe heatwaves in recent years, a trend scientists link to climate change. Extreme heat events have contributed to longer bushfire seasons and more destructive fires, including the catastrophic “Black Summer” bushfires of 2019–2020, which killed dozens of people and destroyed thousands of homes.

State fire authorities said firefighting crews were on high alert across Victoria and neighboring states, with aircraft and ground teams pre-positioned in anticipation of fast-moving blazes. Officials warned that conditions could remain volatile for several days, depending on wind shifts and rainfall patterns.

According to Australia’s Bureau of Meteorology, a large mass of hot air that formed over the country’s outback on Tuesday has moved southeast, triggering a spring heatwave across multiple states. The soaring temperatures have shattered October records in parts of New South Wales, with Sydney experiencing its hottest October day since records began.

Fire authorities are on high alert as dry vegetation and strong winds create ideal conditions for bushfires. Several small blazes were reported in rural areas outside Sydney and Melbourne, prompting warnings and local evacuations in some zones.

In neighboring New Zealand, unusually high temperatures for spring were also recorded, with parts of the South Island experiencing heat typically seen in mid-summer. Meteorologists attribute the weather pattern to a combination of El Niño conditions and persistent high-pressure systems trapping hot air over the region.

Authorities across both countries have urged residents to take precautions against heat-related illnesses and to stay alert for fire danger updates.
