Well off course, define "mastered". As far as i can see, only a handfull of australian institutions have made a sincerely serious attempt, with the current money and science level, and as far i know, all but melbourne have succeeded in breeding them (don't know about australia zoo, and how serious the conditions are at Melbourne). The main difference between platypus and some other mentioned species is that they are, as far as i know not endangered, so capturing a few wouldn't hurt the population as much as the others. I'm not saying these animals should be send by containerloads to shabby animal dealers in the USA/EUR region, but afaik not even a VERY serious and wealthy organisation would not be able to obtain a pair of platypus.

Wouldn't that be the other way round. By that time it could be too little too late. By the time a country is ravaged by war or a population ravaged by disease you could be stuck with a non-viable population. Wouldn't it be best to identify populations that are either low or in rapid decline and act now, rather then later?
I imagine platypus aren't the right example because if i'm correct, their population isn't in rapid decline which brings me to, indeed, the devils. If i'm correct Devils have been kept numerous times in the past outside australia. They've popped up on the species list of Amsterdam Zoo and i know they've been kept by german zoo's in the '60 and '70, and have been bred as well.
I don't completely share your opinion that it would be best for australian scientist to try first. Since the population is on such a decline, but isn't too bad
yet, wouldn't it be better if every scientist in the world would try. If the Australians fail and the numbers on Tasmania drop to >1000 it would be a much harder decision to take even more animals in captivity and then sent them to the rest of the world for them to try. If scientist are moving to and from Tasmania to me it doesn't seem that unlikely they somehow bring the disease over...
I also don't share the opinion that semi-captivity in their homeland is the way to go neither. The sumatran rhino only reproduced twice in the last couple of years, and both where in the USA. Wouldn't it be benificial for some species to be brought to a place which can afford to create hygiene and use science. Without science, Andalas and Suci wouldn't be around and the outlook for the sumatran rhino would, in my opinion, be a lot worse...
Is it ideal? hell no. Do i really care if species are saved under non-ideal conditions, but at least be saved? fraid not. In my opinion the list doesn't contain exemptions anymore, but slowly is showing the science level of some zoological institutions and what they can contribute to fauna. As human encroachment continues and animals are pushed back, i fear but also hope the list will grow, instead of the list with extinct animals growing.
