NSW Liberal MP and vocal coal seam gas supporter Scot MacDonald will be referred to state's corruption watchdog amid allegations he accepted an all-expenses trip to push the benefits of CSG at an agricultural forum.
The NSW Greens claim Mr MacDonald, who was a member of the controversial State Government inquiry into CSG, was flown to Tasmania and put up in a hotel by gas company Santos days after the findings were released.
Commenting on the report at the time Mr MacDonald said "It is difficult to reach any other conclusion other than the coal seam gas industry should be developed as quickly as possible".
Greens MP Jeremy Buckingham told the Herald, it would be alleged Mr MacDonald breached the parliamentary code of conduct.
He claimed there was risk Mr MacDonald would be "unduly influenced by his relationship with Santos" at a time when the State Government was making critical decisions about CSG mining including Santo's current application to develop a major gas field in Northern NSW.
In a statement released on Thursday Mr MacDonald said it was a "shame" Mr Buckingham would "prefer to try and personally smear me, rather than engage in serious debate on coal seam gas".
