Alternate introduced fauna in Australia

I'd love to see established leopard populations in Australia. Leopards are extremely adaptable and will take down a huge range of prey and will inhabit anything from dense rainforest to desert. And without the threat of larger predators, except for dingo packs, you could see some very large leopards emerge after a few generations.

well obviously the guy with "leopard" in his name wants to see leopards in Australia :p in seriousness, i looked it up real quick and see that the Asiatic leopard's range (though broken) extends as close to Australia as Java IOTL, so with appropriate changes in prehistory there could very well be native leopard populations in Australia

interestingly, i think there was something kinda like this in After Man: A Zoology of the Future
 
Thanks for all the feedback.

Are there other poisonous plants than Eucalyptus in Australia?
One of many is Dendrocnide moroides. Deadliest of the Australian 'nettle trees', it's covered all over with stinging hairs that inject a potentially lethal dose of neurotoxins that can leave you in agony for as long as months even if they don't kill you.
That being said, I don't think there's anywhere in the world with just one plant that can make you sick or kill you.
 
Wouldn't lions (or other big cats) be able to work in Australia assuming they ate enough emus and kangaroo? Obviously they'd be confined to the tropical parts, but still.

Lions primarily inhabit plains and require large prey to survive. Would kangaroos and emus be able to sustain a pride? Maybe a small one. Same problem with tigers in that they need large prey and a lot of water.

I'm pretty sure the Kimberley region of Western Australia and the Northern Territory has similar climate to the African savanna, not to mention how the Asiatic lion lived all over Asia at one point (maybe the British bring in that type of lion instead of the African one?). And if the lions couldn't find enough of the prey necessary, evolution would solve the problem by having the lions evolve to a distinct subspecies (because the megafauna is there and all). Maybe in a more grim sense, they could hunt Aboriginals or any other humans unfortunate enough to cross their path.
 
Assume some rich nut sets up one of those giant Texas-sized ranches in Northern or Western Australia


Just to throw some 'do some research dust' in the works! Texas ain't nuthin!
From Wiki-

https://en.wikipedia.org/wiki/Anna_Creek_Station

'Anna Creek Station is the world's largest working cattle station.[1] It is located in the Australian state of South Australia. Its area is roughly 6,000,000 acres (24,000 km2; 9,400 sq mi) which is slightly larger than Israel. It is 1,977,000 acres (8,000 km2; 3,089 sq mi) larger than its nearest rival, Alexandria Station in the country's Northern Territory and over seven times the size of the United States' biggest ranch, King Ranch in Texas, which is 825,000 acres (3,340 km2; 1,289 sq mi). [2]'


And previously

https://en.wikipedia.org/wiki/Victoria_River_Downs_Station

Currently Victoria River Downs has an area of 8,900 square kilometres (3,436 sq mi) The property was once the world's largest pastoral property with an area of 41,000 square kilometres (15,830 sq mi), but following much of the land being resumed it is now less than half its former size, and less than half the size of the current largest, Anna Creek station.[3]


You left horses off your existing list and possibly dingos, along with a long list of birds
