Christopher Pyne's lobbying of South Australian government labelled 'offensive'

Pyne's GC Advisory has been engaged by property developers to fight the state Liberal government's land tax proposals

The crossbench senator Rex Patrick has labelled Christopher Pyne's lobbying of South Australian Liberals on behalf of property developers an "offensive" use of his political connections, while transparency campaigners have renewed calls for a five-year prohibition on post-ministerial lobbying.

Pyne's GC Advisory has been engaged by a group of influential South Australian property developers to fight the state Liberal government's land tax proposals, raising eyebrows given Pyne's recent leading role in the federal Liberal party.
