50c Rise ?
It might actually be close to the truth.
Lets breakdown our humble coffee shall we.
Cost of the water
Cost of heating the water
Cost to purchase the Cup
Cost to purchase the spoon

Cost to .............
I think you see where I am going... I did this roughly and stopped counting at 20 different items involved making the humble coffee, that would on their own attract a portion of carbon tax.
If you were to do it as a time wasting exercise, and said each element was worth 1c, you might be surprised at what the cost impost is going to be.
Keep in mind, once you've added em all up, you need to add the 10% other tax the guvmint wants on this.
