This must be the world's biggest blind box.

I'm actually surprised they had these in stock.

Even as there were fewer drinkers in many other parts of the world, Chinese people were getting wealthier, they were drinking more wine, and it looked very promising.

You know, wine sales were just booming.

This has been really tough for winemakers in places like Bordeaux and Australia, where the industries became to a great degree reliant on Chinese buyers.

Both of these regions for different reasons were particularly favored by Chinese wine buyers and began really catering to Chinese tastes.

And now that demand has really evaporated in China, it's been quite tough for growers in these regions.

So we're seeing winemakers having to pull up vines in both countries and just leave fruit to rot.

So there's a lot of interest on the part of authorities to understand what exactly happened on this trip and why they ended up going to the Philippines.

The Australians haven't said very much, but Filipino authorities have confirmed that they did list Davao, which is a major city in the southern Philippines, as a destination.

Davao is on the island of Mindanao, which has...

hosted Islamic insurgencies in recent decades, some of which have been very violent and have interacted with regional terror cells and even global groups like the Islamic State.

So there are a lot of questions about what exactly the two men would have been doing in the southern Philippines if they received training.

That's something that authorities are actively looking into.
