Thousands of people attended the March for Australia rallies on the weekend... and one of the most common sights in the crowds was the Australian flag.
Many people either flew or wore the flag... as they called for a reduction in so-called "mass immigration".
The images have sparked a conversation about the flag's use and its meaning.
Is it a unifying emblem? A symbol of colonisation? Is it patriotic? Divisive? Exclusionary?
