This stamp issue commemorates two anniversaries: in 2012 it is 150 years since John McDouall Stuart returned from his overland crossing of Australia; and in 2013 it will be 200 years since Gregory Blaxland, William Lawson and William Charles Wentworth crossed the Blue Mountains. 
In 1813, Blaxland, Lawson and Wentworth travelled through Durug and Gundungurra country to establish a route across the Blue Mountains to open up the western plains of NSW for farming and settlement. Others had attempted the crossing before, but the party’s key strategy was to follow a westward-running ridge between the Western and Grose Rivers, travelling for 21 days to what became known as Mt Blaxland. Their expedition led, within a few short years, to a road across the mountains. 

Some 50 years later, Stuart became the fi rst European to make the south–north return crossing of Australia. He left South Australia with his nine companions in October 1861, on his third attempt to cross the continent, reaching the coast at Van Diemen Gulf on 24 July 1862. Stuart raised the fl ag the following day, after fi rst attempting to fi nd the mouth of the Adelaide River. Turning south, the party made Adelaide on 17 December that year. Stuart’s success has been attributed to his experience, his egalitarian leadership style and his lighter method of travel. His expedition eventually led to the Adelaide–Darwin telegraph, (enabling telegraphic communication with the world) and the Stuart Highway. No artist accompanied either expedition, so the source engravings on which the stamp scenes are based were created years later. Emile Ulm’s Blue Mountain Pioneers was published in the 1880 Christmas supplement of the Sydney Mail, and is presumably his impression of the party reaching the western-most point of its journey. The overland crossing is based on George French Angas’ Planting the Flag on the Shores of the Indian Ocean Coast, featured in the 1865 edition of Journals of John McDouall Stuart.

How Fiberstone® Paper is Made
FiberStone® Natural Stone Paper, also known as “stone paper” or “rock paper,” is made from 80% Calcium Carbonate (CaCO) with a small quantity (20%) of non-toxic resin (HDPE- High Density Polyethylene). The Calcium Carbonate in the stone paper comes from limestone collected as waste material from existing quarries for the building and construction industry. It is ground down to a fine powder like chalk and the HDPE acts as a binder for the Calcium Carbonate. So amazingly, 80% of this new paper replacement product is from recycled, reused materials and it’s using no trees, no water, and doesn’t even emit toxic air!
Together these materials create a tough, durable, tear resistant paper that is also a water proof/grease proof paper! Waterproofing paper normally requires a film; now imagine, a soft, smooth, bright white paper that performs like a film but without all the petroleum! It is chlorine free, bleach (commonly used in paper products) free, acid free and totally safe for the environment.

What Makes These Such Green Paper Products

Here’s a quick comparison to put into perspective what this paper means for environmental printing:
One ton of 100% regular virgin pulp paper uses 20 trees, 16,000 gallons of water, and 36,000 BTU’s of energy
One ton of 100% recycled pulp paper uses 4 trees, 9,000 gallons of water, and 22,000 BTU’s of energy
One ton of FiberStone® Natural Stone Paper uses 0 trees, 0 water, and 18,000 BTU’s of energy

The FiberStone® company is also one of the few environmental green printing services available with their waterproof paper label and and green printing services costing only about 10% more than other less eco friendly paper products made with trees.
And the best part is that green paper productslike paper made of stone can still be recycled too to make new FiberStone® Paper or other plastic products such as lumber, furniture, or receptacle bins. FiberStone Paper can also be recycled in the building & construction industry, waste treatment, steel manufacturing, farming, and glass making.
