It looks like a 'pretend' pack, that is, a cheap copy of an original Paddymade rucksack.
What gives it away is the top flap is too short to cover gear when overloaded - the eyelets in the straps show that.
Also, the flaps on the pockets wouldn't stop stuff falling in/out when full - the lid design is incorrect.
Importantly, where's the all important photo of the harness? No waist belt?
Always amuses me when I see more gear strapped on the outside of a pack than what can fit inside.
It may be good for meandering around in open country or on tracks, but not for scrub, etc.
The German design was a classic in Europe but not very useful here.
People like Paddy Palin took that design and modified it for our conditions - more rain than snow, thick scrub rather than open forest and alpine meadows, jungle to desert not just temperate or snowy peaks.
The mods included heavier canvas, more contoured and longer lids to protect contents, a bit less leather, larger volume for real expedition load carrying.
A few bushwalking club members still used them back in the 80's when first generation synthetic packs started to be cost effective and more robust. But the old packs were more nostalgic than useful even then - heavy, uncomfortable, lousy frame, and the skinny leather straps were always a weak point.
It didn't take long for them to be relegated to day walk use or put up for sale in club magazines.
Strapping stuff on the outside of packs is personal preference, but it's very risky - damage/loss of gear, leaving bits of junk in the bush, etc. The only time stuff is typically on the outside is above the tree line in snow conditions.
Looks like pretty much all plantation forests that I have been in in Australia, but I agree in that it isn't native bush.Background to picture looks very un-Australian!
Hard to tell quality unless close ups of stitching, interior and ventral side of pack.
