Well, they have been selectively breed in captivity (at least to an extent)

Interesting. My initial reaction is that, at least initially, importing skunks for furs is one of those ideas which just won't get taken up. Australia's too warm for much in the way of fur-breeding, and skunks do have rather a reputation.
Not to say that it won't happen at all, but it probably won't be very quick. Too many barriers, not enough motivation.
Speaking of introducing species. It just occurred to me that the climate in the Kingyu lands is also seems to be ideal for growing coffee. With cultivation starting to spread to India and the Europe developing a taste for the stuff. Prehaps the Nuttana might be decide they want a piece of the action.
Coffee can certainly be grown in Australia - and, in fact, it currently is, in two widely separated parts of the east coast (far north Queensland, and northern New South Wales - see
here and also
here.). The barriers in OTL were labour costs, until machine harvesting came along recently, and the lower altitude than is usual for coffee cultivation elsewhere. In many cases it may require substantial fertilisers - most foreign crops grown in Australia need that - although I don't have specific information about how much is needed in all cases.
So short version, yes it is possible. Whether it will happen in practice will depend on someone getting the idea, the viability of coffee transportation over those distances, and whether it's cost-competitive when compared to other producers. It would be cheaper to ship coffee from the Caribbean or North Africa to Europe, when compared to shipping from halfway around the world.
Also - and this is perhaps the biggest barrier - the same lands which could be used to grow coffee are also equally-suited, perhaps even better suited, for growing sugar. And sugar
is a sure-fire winner for the Nuttana during this period (1670s-1740s). So the scale of coffee production, if any, would probably be low when compared to sugar.
Ahh ok. There are a surprising amount of Australians floating about NZ actually. Where abouts were you based?
Oddly enough I'd never actually lived in Oz until
after I lived in New Zealand. While there, I mostly lived in the City of Sails.
and they could import civets to help process the beans
Civets are a very, very niche application for coffee processing. (Whether the climate is suitable for civets either, I'm not sure, though it's probably possible). I'm not sure that it would be attractive during this period.
I heard a radio show yesterday that was largely about Ethiopian grains, like
Teff, which would be quite useful in say Australia or northern New Zealand.
Interestingly enough, I've found some passing references to teff growing
wild in parts of Queensland and New South Wales. (See
here.) Irritatingly, I haven't found much in the way of confirmation of that, or in the areas where it is actually grown. But it's believable; according to
here, the old British Royal Botanical Gardens distributed teff seed to Australia (among other places) during the mid-nineteenth century. I also found a passing reference
here to teff being grown in Australia (and South Africa) as a forage crop.
The current cultivation efforts focus on Tasmania, which is less insane than it sounds; the climate in coastal Tasmania isn't too far off that of the Ethiopian highlands. Although different day lengths may pose a problem.
Lots of Andalusian, Sicilians, Greeks or Lebanese (they'd at least have to be Christian in the 19th century)
Given that Sicily has a surplus of population earlier ITTL thanks to the Sicilian Agricultural Revolution, it's possible that there may be more Sicilians ending up in Aururia, too.
