There are several factors which contribute to the death of koalas.
First and foremost, many koalas simply die of old age.
Koalas do have predators which kill them, especially young, smaller joeys. Koalas are particularly subject to dog attacks as they move between trees.
When moving between trees in their home range, koalas may be hit by cars as they cross the roads that intersect their territory.
Koalas are also subject to the disease chlamydia, which affects the koalas' fertility, and eventually leads to their death. Currently, there is no cure for this disease.
Koala populations are being monitored, but current methods have their limitations. The Australian Koala Foundation works actively to monitor koala populations, but they have limited resources. Their view is that the Australian koala population has dropped to below 80,000, but because not enough research on individual populations is being done, they cannot be sure of the accuracy of their estimate. The problem is that the Federal Government remains of the belief that koala numbers are much healthier than that. The Threatened Species Scientific Committee of the Australian Government has put the koala population in the 'hundreds of thousands'. The related link below will also help you to learn more about how koala populations are monitored. It takes you through to various koala research projects currently underway in Queensland.
There are different methods, none of which give accurate figures for koala populations. Most of this work is done by volunteers or researchers who conduct surveys by observations or by electronic tagging.

Declining fish populations in Scandinavia can be attributed to overfishing, habitat loss, pollution, and climate change. These factors have contributed to the depletion of fish stocks and disrupted the marine ecosystem, leading to a decline in fish populations in the region.
The koala does not transmit any diseases to humans. However, they do spread disease within their own populations. A major threat to the koala populations of Australia is the organism chlamydia, which has four major effects:blindnesspneumoniaurinary tract infectionreproductive tract infections, ultimately rendering animals infertile.Scientists are still working on a cure, as this disease is easily spread, and decimating some of the populations on the mainland.
Mainly because of habitat loss.
I THINK THE THREATS ARE NETS AND FISH HOOKS AND PEOPLE KILLING THEM
They don't have enough space and land to live because humans keep expanding properties.

Not just yet. The species is listed as near threatened. Some populations declining, others stable now.
