Well this sounds like a radical shift in position for you from advocating that any "Marxists" in New Guinea move to England or the United States and help us make a revolution here in "the West."
The problem I see here is that a communist has to relate to the struggles as they occur in society. Society is not sitting around waiting for the communists to say "Go !" before moving. Nor will they stop just because some self appointed vanguard teels them to.
What you opened with here sounds very close to the menshevik position in Russia in the late 1800s early 1900s except that they saw that in order to obtain the legalization of trade unions, the removal of the monopoly of landlords and so on they would have to politically overthrow the autocracy. The difference with the Bolsheviks was the strategy and tactics to be used in overthrowing the autocracy. No one, except Trotsky and Parvus, thought any kind of "socialist" revolution was on the agenda in Russia, but Lenin did realize that the bourgeoisie would side with the autocracy and oppose the establishment of a democratic republic. The Mensheviks thought they they should wait patiently for the bourgeoisie to lead the revolution for a democratic republic. Lenin thought that the workers and peasants could form an alliance and make a revolution against both the autocracy and the bourgeoisie. That is what, in fact, actually happened.
The class struggle goes on whether we communists participate or not. We cannot control it. If we are smart we can influence its tempo and help lead it to success. But not if we demand that it unfold the way we demand. if we do that it will go on without us.

Yes, protecting workers' rights, fighting for higher wages, etc. does not make a revolution. If there is a socialist party the workers could of course learn as well about socialism. Only then, when they have become socialists, could they chose to bring the socialist party to power by a revolution. Of course the workers need the peasants with them. One of the first things a workers' government would do is legalize the trade unions, give freedom of speech, improve workers' conditions, nationalize the resources where beneficial, and so forth. For the peasants they would take away the monopoly of the landlords. The difficulties they'd face are enormous, so even after doing all this, the economic situation for the working people might not change much from what it was when 'oppressed', even if now the oppressors are gone.
If workers understand the limits imposed by the material conditions they will not believe any party that makes promises about being able to establish socialism and abolish their exploitation. So in this case they'll still have to wait on a socialist revolution in the industrially advanced states.
But waiting is very difficult, as you know Alex, especially when prospects are so dim; they have no reason or guarantee for an international revolution. Let's assume they are socialist and hold their breath, it's so difficult! They can do nothing, except maybe link up with their brethren in the central nations. And also maybe advise the western workers in how to struggle. I know this shouldn't be the task of New Guinean revolutionaries, but if they don't like waiting and if the western revolutionaries aren't up to the task by themselves, why not.
Now in your scenario, the workers from the start don't expect an international revolution, because they were never socialists and don't like holding their breath. Fine, they're not perfect. Would they sacrifice their lives, without even a hope for socialism, knowing that afterward they not only face the risk, but the certainty of mass enslavement? Is it very difficult to imagine this, but out of their sheer desperateness it can happen. In order to avoid this, the workers should be told that it will be tempting for a government which doesn't accept the need for an international revolution, to enslave and kill millions of their own people to create at most a half-form of capitalism. Turning the other cheek suddenly doesn't seem so bad an alternative. Luckily these aren't the unavoidable choices. The workers can advance the class struggle, to the point of having a socialist government, even in a backward country.
