COAL seam gas shapes as a difficult issue for politicians around the nation.
For the Greens, the road to choose is obvious - oppose coal seam gas because it damages food security and the environment.
For the Nationals, it's more complicated.
Insiders want to strongly oppose CSG anytime it could infringe on farmers' rights.
They're angry at the possibility of pollution of aquifers and the tiny amounts of money farmers are being paid by mining companies where mining occurs.
Privately they want the same thing the Greens do - for farmers to have the right to refuse miners access to their properties.
For an instant a few weeks ago it seemed Liberal leader Tony Abbott agreed, but 48 hours after saying he supported the right of farmers to say no he changed his mind.
The Nationals' refusal to support the Greens' Landholders Right to Refuse (Coal Seam Gas) Bill seems acceptable for now as the Senate continues its inquiry into the issue.
The problem comes if the Nationals fail to convince the Liberals to support farmers' right to say no after the Senate inquiry finishes.
You can bet your bottom dollar Opposition agriculture spokesman John Cobb and water spokesman Barnaby Joyce will make their voices heard on this one - they won't back down.
But there are plenty of pro-mining, pro-big business figures in the Liberal Party.
It could be a bloody battle.
Mr Cobb's good relationship with Mr Abbott is likely to come into play, but may not be enough.
The likely outcome is a compromise where farmers do not have the right to refuse mining companies access to their land, but are better remunerated when mining occurs.
The Nationals would then be sent out to farming communities to sell this as a good outcome.
Interestingly, the Queensland Liberal-National Party's biggest donor is mining magnate Clive Palmer - who has slammed CSG.
The CSG issue is hottest in Queensland and his influence could yet be a factor in dictating coalition policy.
