It's a fragment of a charcoal cave painting found buried in an Arnhem Land cave by David and colleagues.The fragment was both preserved and dateable by being buried in carbon-containing soil But dating most rock art isn't usually quite so straightforward.Julie will be joined in conversation by a number of activists sharing their stories and photos, talking about the issues that matter the most to them and the ways in which they’re changing and have already changed the political landscape of Australia Moderated by Sarah Maddison, with panelists Robyn Laverack, Nayuka Gorrie, and Anna Hush This panel will explore the role of women and feminist politics in building the LGBTIQ rights movement in Australia today.The discussion will bring together the voices of some very different experiences in these struggles, including Mardi Gras pioneer Robyn Laverack; Kurnai, Gunditjmara, Wiradjuri and Yorta Yorta woman and queer writer Nayuka Gorrie; and young feminist campaigner Anna Hush, together in conversation with University of Melbourne political scientist Sarah Maddison.Pillans, who studies the Burrup rock engravings, describes the giant bird painting on the Arnhem Land plateau as a "hint of older rock art".Some researchers say the creature looks like Genyornis which is believed to have gone extinct at least 40,000 years ago.
"Most pigment art contains no dateable carbon, and therefore radiocarbon dating is usually not feasible." What is known as the oldest rock art in the world - cave paintings in Indonesia and Spain — was dated using a more complex method that measures the age of a microscopic layer of minerals deposited after the art is created. Instead of measuring the decay of radioactive carbon, this method relies on measuring the decay of uranium in the microscopic layer to provide a minimum age for the art.Hosted by Julie Mc Crossin, in conversation with activists Betty Hounslow, Teddy Cook, Sally Rugg and Imam Nur Warsame.In a special panel for the 40th anniversary of Sydney Gay and Lesbian Mardi Gras, journalist and 78er Julie Mc Crossin takes a look at LGBTQI activism in Australia from radical liberation and protest in the 70s to the fights we’re fighting today.From the gay liberation movement to the queer politics of today, this panel examines the intersections of feminism, queer, trans*, race, age and Indigenous sovereignty, taking up the most pressing questions of how we can do better as a movement that is committed to justice and equality for all. In this unforgettable Queer Thinking co-presentation with Trans Sydney Pride a diverse range of transgender people will share their personal truth and inner world in an evening of storytelling.With speakers traversing the four decades of Mardi Gras, hear anecdotes from the hilarious to the heartbreaking that explore the community’s history and its unique perception of the world."It's very likely that there is something extremely old in Australia but it's just very hard to date," says David."And there are very few people doing research on rock art." David says there are hand stencils in some limestone caves in North Queensland that are believed to be more than 30,000 years old, and he hopes to be involved in dating these in the future.The bottom line, says David, is that very little rock art anywhere in the world has been dated, including in Australia.But there remain a lot of hints and circumstantial evidence around to support the idea that Australia is in fact home to the world's oldest art.And what are some of the challenges involved in dating them?Many people will be forgiven for thinking that Australia has some of the oldest rock art in the world, but the truth there is no reliable dating to show this.
