(CNN) United States President Donald Trump has found the one immigration policy more controversial than his own, and endorsed it.

Amid heightened media scrutiny over the tragic fate of a father and daughter who died on the US-Mexico border, Trump tweeted pictures of four fliers distributed by the Australian government warning migrants away from attempting to come to the country, adding that "much can be learned!"

That policy, with slogans such as "NO WAY, you will not make Australia home," was the brainchild of current Prime Minister Scott Morrison , who Trump is meeting with Thursday ahead of this week's G20 summit in Osaka, Japan.

As immigration and border protection minister, Morrison in 2013 oversaw the "Sovereign Borders" policy aimed at preventing people smuggling and asylum seekers deaths at sea. While that policy was successful in lowering the number of people arriving in Australia, it achieved this in part by massively expanding the number of people held in offshore detention camps on the Pacific nations of Nauru and Papua New Guinea.

While that policy has become more or less bipartisan consensus in Australia, Morrison has become synonymous with tough immigration policies , often appearing on TV endorsing the campaign slogan "Stop the boats."
