Lynne Thomas opens a large-format book to a photo of two mountains nestled together, tracing her hand along their ridge lines.

The book she is holding helped pave the way for one of the first land rights victories in NSW.
"When you look down the coast, you'll see Gulaga and you'll see Biamanga lying next to her," said Ms Thomas, a Yuin-Biripi cultural knowledge holder.
The two mountains, between Bega and Bermagui on the NSW far south coast, are sacred to the Yuin people.
"When one mountain is destroyed, the other one is affected as well because we no longer have that visual view of our songlines," she said.
Lynne's father, Yuin tribal elder Ted Thomas, was known as Guboo or ‘good friend'. He was an activist at the forefront of the Aboriginal land rights movement in NSW.
Ms Thomas has given permission to use the image of her late father in this story.
In 1978, the Aboriginal community at Wallaga Lake registered a claim for the title deeds to the Wallaga Lake Aboriginal reserve.
The land rights campaign took on a new urgency when intensive logging threatened sacred sites on nearby Biamanga mountain in 1979.
"It was obvious that wood chipping, with a system of roads, stream crossings, and log dumps, was impacting Aboriginal sites," archaeologist and anthropologist Brian Egloff said.
Dr Egloff was given four months to prepare a report to the state government on the cultural significance of Biamanga mountain, recording interviews with the Aboriginal community and settler families, visiting sites, and scouring historical documents for evidence.
"The community was telling us that it was a very important place," Dr Egloff said.
"It was the dreaming place of Jack Mumbulla, his tribal name was Biamanga. And we'd been told that's where initiation ceremonies were held."
In 1979, a NSW parliamentary select committee visited Wallaga Lake for what was effectively the state's first land rights hearing.
Meanwhile, an advisory committee set up by the Wran government was urgently investigating the impact of wood chipping on the five state forests between Bega and Bermagui.
"The opposition to reining in the Forestry Commission in Bega was very, very strong," said Jack Miller, who represented conservation interests on the Ashton committee.
Guboo Ted Thomas, Percy Mumbulla and other elders were not just confronting hostility and fierce resistance from the local community and the forestry industry. They were up against the more conservative members of the state government.
"One cabinet minister said he wouldn't take notice of a black fella who just clapped a couple of clap sticks together," said Terry Fox, who worked closely with Guboo Ted Thomas on the campaign.
"There was a complete denial from some ministers that there were any sites on Biamanga mountain."
Photographs help win battle for hearts and minds
Wesley Stacey was a respected photographer when he bought a block of land with a few mates on the far south coast in the mid-1970s.
"I tried to set up home down here on the coast, right beside where the Forestry Commission were logging," Mr Stacey said.
Mr Stacey and Eleanor Williams joined forces with Mr Thomas to document cultural sites on Biamanga in a series of images that evoked the site's spiritual power and its desecration by logging.
Mr Thomas would choose the sites for Mr Stacey to photograph, often without talking about their significance, and introduced Mr Stacey to a new way of seeing the landscape.
"Ted taught me how to photograph the bush better," Mr Stacey said.
"I had to really try and get in tune with what he was on about, the character, and the mystery of the bush.
One of the enduring legacies of Mr Stacey and Mr Thomas's collaboration is the book Mumbulla Spritual Contact, which Mr Stacey describes as a "propaganda gadget", a photo essay printed in large format to "stuff it in the face of politicians and it would take up most of their view, so they'd have to have look at it".
In 1980, parts of Biamanga mountain were declared an Aboriginal Place and Protected Archeological Area. But the fight to protect the coastal forests between Biamanga and Gulaga continued for decades.
Biamanga and Gulaga National Parks were proclaimed in 1994 and 2001 respectively.
In 2016, the five state forests surrounding the two mountains were reclassified as flora reserves, in recognition of a resident population of koalas — considered a protector custodian of the Gulaga-Biamanga cultural area.
Guboo Ted Thomas passed away in 2002, four years before Biamanga and Gulaga National Parks were handed back to traditional owners in an emotional ceremony.
"That vision that they had kept going," Lynne Thomas said.
"It's like a continuation, like everything we see in this landscape, it just keeps going.
