What could be the possible reasons for the highest concentration of venomous/poisonous animals living in Australia? The most venomous/poisonous (I believe the differentiation is the in the ease of injection of venom and its toxicity) snakes, spiders, and sea animals all live in Australian territory!!! Is there some reason behind this? An unhappy coincidence? Is there an evolutionary reason? A biological reason? An environmental reason? AsaT: Im also Aussie... Im not sure if that´s the reason, though... Ahaha.

Because we Australians live on the edge.

there is a evolutionary as well as environmental reasons , propably , these animals would have not evolved in australia itself they could have been evolved somewhere near australia which could have been submerged now in the sea , in order to protect themselves they could have migrated there , and due to to the threats in their present location nature could have given them these poisonous glands to protect themselves from other animals or human poachers! if you have time search for a map of the world that was nearly 100 million years ago you could see the difference in the ecological conditions and variations , in future if the need for those poisonous organs decreases nature itself takes them back , thats where the idea came " Survival of the fittest" .hope this cures your question. All the best haver a nice day!

Good question .. often pondered about that myself. I don't really know. My guess is 'cause many Australians say exactly what's on their minds - without frills ... and that includes Ausy animals .. I guess the creatures need their space away from humans .. ;) Who can blame 'em ... crickey!!

It may be because of the warmer climate, since poisonous organisms seem to enjoy the warmer climates. Me, not believing in evolution myself have no real answer to they're "evolutionary past."
