Some invasive species that can be found on Mt Everest include the Himalayan blackberry (Rubus armeniacus) and the Himalayan knotweed (Persicaria wallichii). These species have been introduced to the region and outcompete native plants, disrupting the natural ecosystem. efforts are being made to control and manage these invasivespecies to protect the local biodiversity.
According to Australia's Department of Sustainability, Environment, Water, Population and Communities (see the related link below), there are currently 917 described species of reptiles in Australia.
Nothing. You cannot cross these two distinct species. However, the wallaroo is another species altogether, being somewhere in between the size of kangaroos and wallabies. Wallaroos are heavier-set, with stocky bodies, and distinctive dark facial and foreleg markings.
No but I have read about some stories of them being seen in Australia, These are believed to be ones that escaped captivity.
First of all, if you're a creationist, ask your local representative of whichever divine being you believe in. Ignore the rest of this post, as creationists will consider it heresy. It has to do with genetic drift - the foundation of evolution. Australia is a very isolated continent, lacking any land bridge to another continent. It is thus isolated. Furthermore, the climate of Australia differs significantly from the other 6 (for that matter, the other 6 also have unique climates), meaning adaptations in Australia need to solve a different set of problems. When a population of a species is isolated from the rest of that species, as those of Australia were whenever continental drift separated Australia from what was left of Pangea (the megacontinent from when all of the continents were connected), its genetic traits slowly begin to differ from the original species - this is called genetic drift. Eventually, instead of 2 separated populations of a single species, we have 2 separate species. One of these species is in Australia, the other in the Pangea remenant (probably just Eurasia at that point). Why they are so radically different in Australia than in most other continent combinations is primarily due to the amount of time since Australia separated from Pangea. South America and Africa split fairly recently. The geological evidence has not yet eroded away, and is easily identified by geologists. Furthermore, the genetic differentiation has not been enough to make a significant difference between Jaguars and Leopards (well, from a layman's perspective). Just going from the amount of genetic drift, I'd suggest that Australia split from the other continents fairly early in the disintegration of Pangea, perhaps even the first significant land mass to split off (other than possibly Antarctica, which is barely relevant in a discussion of evolutionary diversity.
It's an introduced species such as rabbits being introduced into Australia.

Yes, species are being introduced to new ecosystems accidentally through activities such as global trade and travel. Additionally, some species are intentionally introduced into new ecosystems for various reasons, such as pest control or agriculture. These introductions can have both positive and negative effects on the receiving ecosystems.
No. Koalas are not native to Western Australia. They are restricted to the native eucalyptus bushland in the eastern half of Australia, excluding Tasmania. Having said that, however, they have been introduced to small pockets of land in Western Australia, but they are not recognised as being a Western Australia species.
Yes. No different from cows being introduced to Australia or North America.

No. Australia has strict controls on exotic pets. It's a pity these controls weren't introduced from the time of the First Fleet, as Australia also has the distinction of being the continent which has seen the extinction of the most native species in the last 200 years.
An introduced species is a species that is living outside its native environment. This happens as a result of humans, either accidentally or on purpose. They can cause damage to the environment that they are introduced into. One example is the black rat being in North America even though it is from Europe.
I recommend eating the fish.
One example of a new species introduced to the US is the Burmese python in the Florida Everglades. Originally from Southeast Asia, these snakes are now considered an invasive species in the area, negatively impacting native wildlife populations. Efforts are being made to control their spread and protect the ecosystem.
It is a weed, Echium plantagineum (Purple Viper's Bugloss). Originating in Southern Europe, in was introduced in Australia as an invasive specie. In Southern Australia, it is called Salvation Jane. It is poisonous to many grazing animals, especially horses. Being annual, it requires constant control.
The mind of those who introduced the White Australia Policy was that without the policy Australia would be overrun by the Asians. People opposed to the intolerant bill pointed to Canada and New Zealand for example of countries with out such policy who were not being overtaken.
