Places we cherish are threatened
Western Australia is one of the world's great foodbowls. Shale gas fracking has the potential to threaten the water that family farmers need to keep their farms productive - shale gas fracking presents a real threat to WA food security and to valuable export markets.
Fracking also threatens to industrialise some fo the natural landscapes that we cherish - the Kimberley, wildflower country, Ningaloo...
If a shale gas fracking industry is allowed to develop unconstrained, the Mid West, Gascoyne and Kimberley will soon be pockmarked by tens of thousands of gas wells, along with all the roads, parking bays and pipelines that an operating gasfield requires.
Already in the US, 450 000 wells have transformed landscapes into an unsightly spider's web of wells, tracks, wastewater ponds, pumps and pipeline infrastructure.
And what happens when the industry leaves town? Who is going to clean up the mess? Or will we just be left with a legacy of abandoned wells, leaking pollution into our water sources.

We should consider cumulative risks
We should consider the cumulative risk of gas fracking – that is, the risk that something might go wrong at any one of tens of thousands of wells, and the impact that that number of wells will have on the surface. The sheer scale of development characteristic of gas fracking increases the odds of something going wrong, and of the public being exposed to the risk of groundwater contamination, surface water pollution or air pollution.
Scale of damage
Much of Western Australia’s shale and tight gas lies below some of the most beautiful and bio-diverse regions in the world – the wildflower region of the Mid West, the Ningaloo region and the Fitzroy River region in the West Kimberley.
A typical gas well site has 3.6 hectare surface footprinti] - and there is the potential for 25 000 wells in the Mid West and 100 000 wells in the Kimberley alone...
You do the maths – the gas fracking industry is going to change Western Australian landscapes – and forever - because it is impossible to completely rehabilitate an abandoned gas fracking site. From the European Commission Report on Shale Gas Fracking:[ii]
The evidence suggests that it may not be possible fully to restore sites in sensitive areas following well completion or abandonment, particularly in areas of high agricultural, natural or cultural value... this could result in a significant loss or fragmentation of... valuable farmland or natural habitats.

Speed of development
Gas fracking fields can emerge with alarming speed. In Queensland and New South Wales, despite vocal community opposition, several thousand coal seam gas wells have been drilled within a few short years.
The Barnett shale in Texas grew from 400 gas wells in 2004, to well over 10,000 wells today.
Are we ready for that in Western Australia?
