In the video it talked about how and bit why Australia grew to federation.
The bigger and more populated colonies thought they had to supply the other colonies I guess that would weaken New south Wales and Victoria the powerful colones. The smaller colonies thought they would be controlled by the more powerful colonies. The colonies started and stayed different to the others even you tried to travel from Brisbane to Melbourne you would have to switch trains because the tracks were different.
Why would the make same size track because it would save time building? Why didn’t britian just colonize the whole of Australia?
I believe that the train tracks thing is just wrong you could save time before it’s video I thought they were more a like.
