Two Vietnamese men have been found near the crocodile-infested Daintree River in northern Queensland, Australia, while as many as 24 illegal migrants are believed to be in hiding in the area.

The two men found were believed to have been on board a fishing boat which foundered near the mouth of the Daintree River in north-east Australia. Others from the boat are thought to be hiding in the area.

The two Vietnamese men were rescued by local fishermen on Monday.

Queenslanders Justin Ward and Barry Preston were on their boat and just about to start fishing they noticed the two Vietnamese men stranded in the mangroves near the river. Ward said the two men looked worried, Channel 9 News reported.

The two Australians picked up the two Vietnamese on their boat and had the men help them lift their crab traps from the river and showed them around the Daintree area, which is known for being infested with deadly salt-water crocodiles. The four men took selfies, enjoyed a few beers and chatted.

Ward said the first thing the migrants asked was to be taken to a market. However, that day the markets were closed. Despite the Australian’s compassion for the illegal migrants, they ultimately handed the two over to authorities.

Only one day earlier, a migrant boat reportedly entered the Daintree river. Locals alerted authorities after seeing a large number of people escaping from the sinking boat, SBS News reported. Australian Home Affairs Minister Peter Dutton said this was the first time a smuggling boat has made it to Australian shores in four years.
