Answer:
First, analyze what format you want your essay to be in. If your assignment requires something that is more linear and statistic based, try writing your essay in an expository way that expresses facts, information, etc. However, if you are writing your essay in a way to convince people to let refugees into Australia- try a persuasive essay.
To start your essay, try expressing a current situation at hand. You can start your essay by addressing an experience of a refugee migrating to Austalia, or introduce your essay with a problem/situation that requires refugees to migrate. If you plan on writing a persuasive essay, you can add written elements such as reasoning to why you believe refugees should be accepted into Australia. If it is an informative essay, try incorporating statistics and factual evidence to solidify your arguments and statements throughout your essay. You can use a point such as refugees needing shelter and migrating as a means to escape their unstable homelife, with statistics of their current unhealthy conditions.
