Being one of the continents without primates (apart from humans), it would always be an interesting thing to think about if monkeys/primates were introduced to Australia. Would they be a pest and bother the nation? Or will they not affect the ecosystem in Australia and mind their own business? Let's take a look at if monkeys/primates were introduced to Australia, and what affects they would have on the country.
First, we will need to examine where they will go, to be more specific, which biome they will belong in. Australia is filled with wonderful biomes, such as the desert or the mountains. In the places they are native to, monkeys/ primates mostly inhabit forests. The uneducated one will think that Australia is all desert, as seen in movies and TV shows. But in reality, Australia has a diverse mix of biomes, though most of Australia is covered in desert. There are no sorts of monkeys/primates living in deserts, as the climate is too dry and there is not enough food and water. Mangroves may be a good option, as monkeys/primates in the wild do live in mangroves. But there are also moist forests and rainforests, which are also suitable habitats for monkeys/primates. Dry forests though are probably not too fitting, as the vegetation there is too dry, and trees are mostly not too close together, as monkeys/primates need to jump from tree to tree, and the trees have to be close together for that. 
Now we should examine what effects they would have on the local environment. Monkeys/primates may be preyed upon by large snakes such as pythons, but in turn the monkeys/primates may prey upon python eggs, but monkeys/primate may escape pythons with their tree jumping techniques, only being caught if it is not alert. There are also saltwater crocodiles, but they are river-dwelling creatures, so it is very unlikely that they would prey on monkeys. Since the only threat to monkeys/primates in Australia are large snakes, then monkeys/primates would probably become an environmental pest very quickly. They might outcompete native species like the tree kangaroo, and would be a big problem to the already endangered Bennet's tree kangaroo, as monkeys/primates may over consume their normal food, causing the tree kangaroos to starve. The monkeys/primates may also carry diseases that are dangerous to the native wildlife, an example being the rhesus monkey that was introduced to Florida, expect the disease they carried was deadly to humans. Monkeys/primates may also be a pest in urban areas, as they may enter towns and become a problem for locals.
So is introducing monkeys/primates to Australia be a good idea? Well, no, as they may carry diseases that are deadly to the native wildlife, they may be a pest in urban areas and most importantly they will outcompete native wildlife.
