>was equally successfully because its troops were more INVENTIVE.<
There is a thesis on the First AIF, technology and tactics etc that may help you with that. It is at;
The website mentions among other things where they recieved their training from and how they executed their organization at the line. Very informative.
As to inventive the Australians operated well at smaller levels and as small units. You often read that officers explained to the troops objectives and why they wre going after what they were. So when an officer died or the troops got cut off they werent paralyzed wondering what to do, they were still able to achieve their objectives, predominantly because they knew their objectives and its place in the broader scheme of things. Information the average Tommy probably did not get. It would be interesting to know if the Canadians, Guards and Fusiliers had that sort of flow of information between their higher officers and lower officers and men.
Another thing that helped the small unit in the AIF was due to the losses the AIF had taken they were short on manpower in late 1917 and 1918. To overcome the lack of manpower they gave their platoons more Lewis Guns. As small units they were very capable of laying support that a larger British unit would only be capable of.
The other thing that may have helped is the "'ave a go mate" or "'ave a crack at it" attitude. In the trenches the British had specialized platoons of snipers that fired from the trenches day and night. They didnt do fatigues etc. The Australians instituted the same system in France but the average Australian soldier is unable to sit on his hands for more than two seconds and within a couple of days they were all firing as if they were snipers. Must have made things uncomfortable for the Germans in their sector.
In the air I dont know, the AFC pilots did a whole bunch of stupid stuff that is funny in retrospect, but being lads of 20 - 24 which every air force was then, I doubt they got up to any worse shenanigans in the air than other Squadrons in other Air Services.
On the Avro 504K, none reached Australia or Point Cook until late 1918. They were assembled at Marrickville by a local company who used Australian Hardwoods in the aircraft. The wood added an extra 50 - 100 lbs (IIRC)
