Hey, wash you mouth. Old School BMX is cool, particularly when you win your class in our retro series [over 40's] even after missing round one completely.
As for your problem, I don't know that I can add anything at all since you have obviously done your homework, although power cable, in conduit, is supposed to be at a minimum of 600mm as you mentioned & telephone cable, in its proper 'white' conduit must be at 300mm.
The act requires that phone cable be at a minimum of 300 with a separation to power of 300.
The voltage drop in the phone cable over 100m will be almost unmeasurable over 0.040 wire but use 0.064 if you have any concerns. I would suggest 2 pair 0.064 HJ [hard jacket] which was intended to be direct buried, but install it in conduit in any shared trench. It will take a direct hit from lightning to kill it. This assumes that you will be running just a standard phone service off the end of it.
I'm sure that you know the colour code, white/ blue for pair 1 & of course red/ black for pair 2.
A five pair cable is also made, but the stuff that I used was 0.032 wire gauge which is the thickness of coarse hair & too thin for your needs.
Sorry that I don't have anything more to offer.
P.S.
The longest distance from an exchange over which we had a working phone service in my area was about 25Km. It wasn't the best, but was within specifications [just] & this was over cables that did not excede 0.064mm in conductor diameter.
