Australia Post has been trying to make a few stand out issues.
It takes two 35c stamps to make up the cost of a standard letter rate and this issue is near to the last of the 70c issues released as well.
Also there has not been to many make up stamps ever issued that take two to make up the cost of a standard letter rate item.
Plus on the 4th Jan 2016 the standard letter rate will rise to a $1. It is an interesting time for the very modern Australia issue collector. This 35c stamp is a commemorative and in multiples on cover is going to be a very hard item to get.
The southern lights issue 2014 as another example.
It could be said that the printer got the stamps of the same colour out of order but I think not.
