Yeah that list seems correct, however, not knowing the LD50 of all the snakes i couldn't say. I much prefer to see them listed as top 10 Most Dangerous. Going by venom toxicity and yield is all good and well but it's alittle pointless when it comes to the danger aspect.
Going by the danger side of things...you would see either the eastern brown or coastal taipan in first place, probably followed by the tiger and then alot of others not actually on that list, such as......BBBS, RBBS, Copper head, King brown.
