For example, primates made it from mainland Africa to Madagascar. Arctic foxes made it to Iceland. Clouded leopards made it to Taiwan. Giant salamanders made it to Japan. Etc etc.
Is the Tasman Sea really THAT vast?

A lot of these animals didn't "make it" to anywhere, they pre-date the landmasses in question being separated. Salamanders existed when earth looked like this-  So they didn't have to voyage over the ocean to get to japan, they just stayed put and managed to survive in the creeks and rivers on the ground that later became japan. Arctic foxes presumably walked over the... ice, during the last ice age. Clouded leopards wandered over the land was between mainland asia and taiwan during the last glacial maximum.  Lemurs are genuinely a little strange, they do believe they must have really floated over to madagascar on some debris. But it still needs to be understood it was much closer during the glacial maximums. New Zealand was always way too far from Australia. See this map of the world during the glacial maximum. - linkAnother showing the ice-  |

But I guess there is one “exception” to the OP; aren’t kiwis related to ratites? Australia has emus and cassowaries. |

If you go back 80 million years both Australasia and "zealandia" were attached to Antarctica, so there was a connection at some point. The ratite ancestor perhaps is just that damn old? The fact there are/were also ratites on madagascar, mainland Africa and South America would seem to support this idea. The "Gondwana" continents seem to have ratites.  |

That middle picture helps to explain why India and Africa share rhinos, elephants, large bovids, lions, and leopards. |

Well things get complicated actually, leopards and lions actually descend from European Jaguars. They only moved down into Africa and India after those continents collided (ditto for jaguars moving in to south america).
I'm not actually well schooled in the natural history of rhinos and elephants. I think they probably came from Laurasia though (the top continent).
