In early 2020, as Australians were being locked down, something strange was happening in an inner-suburban hotel in Brisbane. A group of men, previously invisible to most Australians, gathered on the hotel balcony wielding hand-made banners. Who were they? And how did this moment change the minds of middle Australia? It's 10 years since Kevin Rudd declared "no one who arrives by boat will ever settle here". The fallout catapulted thousands of lives into a decade-long limbo. Two of the men on that Brisbane balcony join host Natasha Mitchell and other guests at the Brisbane Powerhouse as part of the Portraits of Protest exhibition.

It's possibly the greatest ever example of artistic censorship in Australian history. Police have requested hip hop to be taken off online streaming platforms, stopped bands from performing in Australia, and amended visa regulations so local hip hop artists can't perform overseas. Their claim is that hip hop is inciting violent and criminal behaviour. But it's an old debate that first emerged in the birthplace of hip hop more than two decades ago. Osman Faruqi shines a light on parallels to the hip hop wars of 1990s America, the role of police bias and profiling, and concerns for free speech more broadly.

From apps that help us swim safely to using Crispr to cut the genes of box jellyfish to technology that identifies the source of a barramundi or coral trout at the fish market, science is at the fore-shore of keeping our oceans and our lives safe.

What do the streets feel like where you live? Unsafe for kids to ride to school, big busy highways, limited public transport, cars reign supreme? From electric vehicles to bike-friendly buses — be inspired by these globally renowned movers and shakers. They're using the regional town of Bendigo and international case studies to re-imagine how we can live and move. Transport accounts for a staggering quarter of global greenhouse emissions. Could one Australian town lead the way and hit zero transport emissions by 2030?

Three influential women explore the power, the politics, and the cost of speaking out. 

The history and development of the nuclear industry is shred in secrecy and contradictions. And its future is throwing up more questions than answers. A scientist, a historian and a poet consider the economic, scientific and social realities of nuclear technology. They discuss how the lessons from the past might shape an uncertain future, and the possible consequences of playing God.

Are Greek-Australian's now considered to be 'white' in Australia's colourful social fabric? A panel of prominent Greek-Australians discusses questions of identity and belonging. As they have evolved into one of the oldest migrant groups in the country, is the era of Greek 'otherness' over? And what role did anglicising surnames play in our journey towards acceptance?

"Are they a girl or a boy?" That question is often asked about a newborn. But what if you're born with genetic variations in sexual development, also known as intersex conditions, and possess both typical male and female physical traits? New legislation tabled in the ACT is set to limit the scope of medical treatments and surgeries for such children. Intersex activists have campaigned hard for the law saying the human rights of the child to bodily autonomy is paramount. But some argue not all lived-experience voices are being heard, and are concerned the new laws could criminalise clinicians, carers and parents.

The best of talks, forums, debates, and festivals held in Australia and around the world.

Meet some climate refugees of a different kind. From the Western swamp tortoise to honey ants to whales, can they just up-stumps and move house if things get too hot under the collar? From understanding First Nations science to breaking up the siloed western conservation practices, are there better ways to make life possible for every being on a warming planet?
