Thousands of anti-war protesters clashed violently with police on Melbourne’s streets yesterday, fuelled by anger over a major arms expo where defence companies are showcasing their latest weapons and technologies.
While many protesters focused on Israel and its war in Gaza, Australia’s arms trades with other nations are also under scrutiny.
What do we know about where Australia sends its weapons, and who we buy them from? We analysed data from the Stockholm International Peace Research Institute and created five infographics to reveal Australia’s international weapons exports and imports. Military expert Lauren Sanders also explains why this information is so hard to find.
And with Kamala Harris and Donald Trump clashing yesterday in the US presidential debate, we also asked three experts to weigh in on who they thought performed better– and their most memorable moments.
