Mr Morrison said Australia would stand up to autocrats who sought to bully others, pointing to a Chinese PLA Navy laser attack on a RAAF plane and the Ukraine crisis.
"What is concerning us is the increasing cooperation between authoritarian regimes around the world," he told the Tasmania Talks radio show on Monday.
"And that's why countries like Australia have been standing up and standing up to them.
"It's an increasingly dangerous world. And Australians have to stand up for what they believe in and not go down the appeasement path."
His comments came just hours after Defence Minister Peter Dutton said it was difficult to see how Russian President Vladimir Putin hasn't given troops the order to invade Ukraine.
Some reports indicate more than 150,000 Russian troops on the border with a further 30,000 in Belarus to Ukraine's north, providing Russia with a shorter path to Ukraine's capital Kyiv.
Speaking after reports from US intelligence and warnings from British prime minister Boris Johnson the conflict would be the biggest war in Europe since 1945, Mr Dutton said invasion seemed inevitable.
"Troops continue to build up, the presence of the ships in the Black Sea, the cyber attacks, the false flag activity, it's all pointing in one direction sadly," he told the Nine Network on Monday.
"We just don't want to see women and children as the victims of another war, but it seems that is the path that Vladimir Putin is set on embarking."
Mr Dutton said any conflict would have a knock-on effect for the world and while there are hopes of an 11th-hour reprieve, "There is no sign of one yet".
There has been sporadic shelling between the divide of Ukrainian government forces and Russian-backed separatists, with US Secretary of State Antony Blinken saying Russia is on the brink of invading.
Foreign Minister Marise Payne met with her Ukrainian counterpart in Europe as the pair attended a security conference in Germany.
Dmytro Kuleba said he and Senator Payne discussed opportunities for providing military-technical support.
"Grateful to Australia for standing by Ukraine at this tense time of the security crisis created by Russia," Mr Kuleba wrote on Twitter.
The meeting comes just after Australia officially attributed malicious cyber activity against Ukrainian banks to the Russian Main Intelligence Directorate, known as the GRU.
Australia will continue to provide Ukraine with cybersecurity assistance and further security training for Ukrainian officials in light of the February 15 and 16 attacks.
Mr Dutton said there is scope to provide more support to Ukraine through "basic equipment" and Australia would look at each request from the country.
"But we need to be realistic in these circumstances as the troops amass and the ships are on a particular course and now occupying the Black Sea," he told the ABC.
Home Affairs Minister Karen Andrews said Australia is reviewing what visa support it could offer Ukrainians if conflict does break out.
"There are ways that people can indicate that they wish to come to Australia and resettle (and) that is through our humanitarian programs. That is what will be our focus," she told the ABC.
"We will be going through the process of looking at what is the best way to support people right across the world (but) the only way to come to Australia is legitimately and legally."
