Almost completely cut off from the outside world, Mrs Newnham spent days patrolling for spot fires and "unloading by uploading to Facebook".

About 15 months later her stress-induced musings - equal parts heartbreaking and informative with a dollop of humour - have been turned into a book From the Inside: The first nine weeks of the Black Summer bushfires in the Upper Murray.

"Initially I was posting to communicate with family and friends in a simplistic way about what was happening here, because we were cut off from communications," she said.

"We still had our satellite internet so it was the easiest way to get a lot of information out quickly to a lot of people without tying up our time.

"After a while it became a bit of a psychological boost."

Unbeknownst to Mrs Newnham at the time, residents across the region were reading exhausted posts to gleam insights about "the roaring red monster devouring the Upper Murray".

As the first anniversary of the bushfires Mrs Newnham was inspired to compile her posts, experiences and the photographs into a self-published book.

"The process of putting the book together was quite cathartic," she said.

"A lot of (the posts) I did on the spur of the moment and therefore they are quite raw but at the same time they're really descriptive.

"I think it reflects a lot of the experiences of other people too, particularly those from farms who were in the dead centre of all - the flames and smoke and the horror of it all."

For the book's first run Mrs Newnham ordered 300 copies, planning to give 100 to those who helped the community in the aftermath of the fire and assuming most of the other copies would sit in storage.

Only weeks after receiving the first batch, she's had to order a second run.

"It's just amazing I initially thought I'll print 300 books but I'm sure I'll have trouble getting rid of them," she said.

"Primarily, I put it together as a reflection of our experience and to give people some insight into the fact everything is survivable really, it's just your attitude towards it. You just have to keep pushing on, you can't get down and gloomy, there's too much to do.

"I also wanted to produce something that we could gift to people who were so generous to us during the episode and aftermath of the fires."
