Oops, sorry for bursting your conspiracy bubble.

.. we have lost the 250 gram category, we are now paying double of more for every auspost service since its inception .. the rate to send parcels in this country is prohibitively expensive to the point in many cases you just don't bother attempting .. overseas rates have tripled in some cases .. you are just stirring the pot as any blind freddy can see that auspost is a rippoff compared to before corporatisation .. if my pay had increased at the same rate as auspost rates I would be a very happy person .. couriers do not deliver to all points of the country so is unviable for many purposes hence I say that auspost is a monopoly practices monster .. their price structure is directly focused on flexing their muscle to disuade new players attempting to piggyback through their service .. basically everything you have said is a big load .. You are quite deluded ..
