This photo from the State Library comes in black and white as well as colour versions, so I guess it was sold as a postcard.
It also features in the Leader Newspaper published on 30 August 1902. The caption says the road was recently constructed with an unemployment scheme.
I clambered all over those soggy and leach infested hills as a young forester and I reckon the photo was taken a couple of km south of Gunyah Junction on the Toora-Gunyah Road, near the turn off to the old Mt Fatigue firetower.
The scrub on the left side of the road is the current Gunyah Rainforest Reserve, with the monumental Gunyah Tree nearby.
Ironically, this area of about 2000 acres was set aside in June 1882 for “growth and preservation of timber” after concerns from early foresters about the wastage of forests in the hasty, and ultimately failed, scramble to settle the Strzelecki Ranges for farming.
Interestingly, the trees are labelled black butt which was an early, and now rarely used, name for mountain ash (Eucalyptus regans), or “King of the forest”.
As you can see the understory is sparse but that’s not uncommon for dense and mature mountain ash stands.
I’ve seen it suggested that the understory looks as though it’s been recently burnt, and while it’s hard to be certain, bushfire generally kills mountain ash trees, and the photo was taken three years before the major bushfires in 1905-06 which swept through the hills behind Toora and killed 7 people.

Victoria’s Forests & Bushfire Heritage 
Thanks Peter McHugh. Nice pics. They were called Black Butt because their butts were blackened by frequent mild fire. When Strzelecki went thru in 1840 it was 20 yr old forest generated by megafire after the Yowenjerre were virtually wiped out by smallpox in 1789, and healthy open forest turned to dirty scrub. When Howitt saw it there was another age class from Black Thursday 1851 megafire. When settlers started clearing in 1870s they found clay cooking ovens, spearpoints, stone axes and grindstones. Mountain ash, like all eucs in Aus should be maintained with mild fire.
