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.
Koalas die because of humans who hunt them for their soft pelt. The koala's biome is being detroyed by people seeking farmland or selling lumber. Koalas have many enemies doing harm to them. tanner
Koalas, as a species, are not "dying", or in any immediate danger of extinction. They are not listed as endangered, although they are classified as vulnerable or threatened in some localities within Australia. They are at risk from numerous threats.
Having said that, however, just because the species is not officially threatened does not mean that they are free from threats to their future existence.
The chief threat to the koala is habitat loss. Koalas inhabit prime land which man has decided is better used for housing developments. Not only do the koalas lose their sources of shelter and food, they are subject to dog attacks and being hit by cars as suburbia extends further outwards. A prime example of this is southeast Queensland, where koala numbers have dropped to 60% less than what they were a decade ago, entirely due to increased development - and where they now face extinction by 2020.
Koalas are territorial, and they live in complex social communities where each member has a certain number of trees within its territory. When access to these trees is cut off by new roads, the koalas will still try to cross the road, and risk being hit. Relocation of koalas is rarely successful because their territorial and social habits are largely misunderstood.
Another significant factor is predation by introduced species such as dogs and foxes.
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. At the best of times, the koala is a slow breeder, usually producing just one joey a year.
Koala populations do sertainly seem to be declining, although various bodies would disagree with this. The Threatened Species Scientific Committee of the Australian Government has put the koala population in the 'hundreds of thousands'. However, the Australia Koala Foundation believes a more realistic outlook is that koala numbers in the wild have dropped to below 80,000.
Current estimates suggest the figure could be anywhere between 40,000 and 100,000.
While parts of Australia enjoy a very healthy koala population (e.g. southern Victoria and South Australia's introduced koala population on Kangaroo Island), in other areas, the populations are clearly declining. There are no longer any viable koala populations on the NSW mid coast, for example, while in southeast Queensland, koala figures are down 60% from a decade ago.
Although koalas are not officially endangered, there are several factors contributing to the high number of koala deaths each year.
The main reason koalas die is because of habitat loss. Koalas inhabit prime land which man has decided is better used for housing developments. Not only do the koalas lose their sources of shelter and food, they are subject to dog attacks and being hit by cars as suburbia extends further outwards. A prime example of this is southeast Queensland, where koala numbers have dropped to 60% less than what they were a decade ago, entirely due to increased development - and where they now face extinction in the next decade..

Koalas are not bears.
As a species, they are not in any immediate danger of extinction, though certainly they are "vulnerable" in some parts of Australia.

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.

Mainly because of habitat loss.
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.
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.
