Scott Morrison has heaped praise on US President Donald Trump for trying to strike a deal with North Korean leader Kim Jong Un to denuclearise the Korean peninsula.
After the two leaders failed to reach an agreement during a summit in Vietnam last week, the prime minister said achieving denuclearisation in North Korea was a difficult task.
"His determination to keep pressing forward - there will be frustrations - but I really commend his heartfelt commitment to try and make some progress in this area," Mr Morrison told reporters in Sydney on Monday.
Foreign Minister Marise Payne said the two-day talks "continued a path in the right direction".
"These are very complex matters," Senator Payne said.
"We know that they were never going to be resolved overnight, and I commend both the president of the United States and Kim Jong Un for the engagement they have had during these sessions."
The federal opposition is similarly upbeat about the Vietnam summit, with Labor senator Penny Wong saying "the only thing worse than no deal is a bad deal", and it was positive the two leaders were talking.
