That would of great benefit to the region. The Indonesian imports have quickly become assimilated into the regional population and their first generation offspring are now being inbred to mates at Taronga, Adelaide and Hamilton Zoo.
Since most of our tigers descend from European imports, I’d recommend looking to the US again. Though their population is partly derived from European imports; they’ve sourced a few wild born founders of their own, including Kerinci (1985-2004).
Importing from Indonesia is clearly a challenge (not even Taronga could achieve it when they tried in the late 2010’s), so personally, I’d go the US route. Importing from the US is no picnic (two year process), but it’d be nice if Ramah and Zayana’s line wasn’t the only new bloodline over the next decade (even though I personally will enjoy them receiving regular breeding recommendations at Auckland Zoo

).
