Frequently asked questions
Science fiction films typically explore speculative concepts, often involving advanced technology, future societies, space travel, or extraterrestrial life. They use these elements to tell engaging stories, frequently examining what it means to be human, the impact of scientific progress, or challenging our understanding of reality. You’ll find a blend of imagination and thought-provoking ideas.
While many top-tier sci-fi films are available to stream in Australia, availability can vary. Streaming services regularly update their libraries, so a movie might be on one platform today and another tomorrow, or even rotate off services entirely. Our list aims to provide current availability, but it’s always a good idea to double-check.
Our selections are carefully made using a clear methodology. For this sci-fi list, we focused on films with high IMDb ratings to ensure popular and critically acclaimed choices. We then cross-referenced these with Australian streaming availability to offer you genuinely streamable recommendations.
The sci-fi genre is incredibly diverse! You’ll often come across space opera, with its grand adventures and epic conflicts, like Star Wars, while dystopian futures, showing bleak societies, are another common theme, as are mind-bending thrillers that play with perception and reality. Other popular types include cyberpunk, alien invasion stories, and time travel narratives.
Our list embraces a wide range of sci-fi films, spanning various eras. You’ll find beloved classics that have stood the test of time alongside more recent blockbusters. The aim is to give you a well-rounded selection of the genre’s best, regardless of their release year, all ranked by their IMDb scores.
The IMDb rating is a widely recognised and respected metric, reflecting a large audience’s collective opinion on a film’s quality. By using it as our primary ranking factor, we aim to provide a credible and objective foundation for our “best of” list, making it easy for you to identify highly regarded movies.
Some of the films on our list might occasionally be available on free streaming services in Australia, particularly those with ad-supported models. However, the majority of the top-rated sci-fi movies typically reside on subscription-based platforms. We’ll always indicate which service hosts each film.
We strive to keep our content current and relevant. Streaming availabilities and IMDb ratings can shift, so we regularly review and update our “best of” movie lists. This ensures that the information you find here is as accurate and helpful as possible for your next sci-fi movie night.
