Environmental pressures on Australian ecosystems: fish migration blocked, koala overpopulation, severe weather events, ocean heat record
Key Questions
How is climate change impacting fish in northern Australia?
New research shows land barriers created by climate change are trapping fish in northern gulfs, threatening commercial fisheries such as brown tiger prawns.
What is being done about South Australia's koala overpopulation?
A boom in koala numbers risks mass starvation, leading to a proposed $34 million fertility control program to manage the population sustainably.
What weather events are adding pressure to Australian ecosystems?
Cyclones Narelle and Alfred, combined with a forecast Super El Niño and record ocean temperatures, are increasing environmental stress on wildlife and habitats.
New research shows climate change is trapping fish in northern Australian gulfs due to land barriers, threatening fisheries like brown tiger prawns. South Australia's koala boom could lead to mass starvation, with a proposed $34M fertility control plan. Severe weather systems (cyclones Narelle, Alfred) and forecast Super El Niño add to environmental stress. New: world's oceans hottest on record for June 2026, with El Niño amplifying – threatens stronger cyclones, heatwaves, and marine ecosystem impacts for Australia.
