Australia's 600,000 Muslims have originated from more than 70 countries around the world.
Ramadan is the ninth month of the Islamic calendar, observed globally by an estimated 1.8 billion people, as a month of fasting from sunrise to sunset, prayer, personal reflection and community. It lasts 29-30 days, from one sighting of the crescent moon to the next.
It's followed by Eid al-Fitr or "Festival of Breaking the Fast", celebrating the end of the month-long fasting. The three-day celebration starts with Muslims praying together and is also an occasion for families to get together and eat traditional foods only made during Eid.
