The alleged removal of a senior live export veterinarian from her job with the Department of Agriculture reveals the level of control the live export industry has over the Turnbull-Joyce government, Greens animal welfare spokesperson Senator Lee Rhiannon said.

The ABC's 7.30 report "Vet removed for exposing appalling conditions on live export ships" was screened last night.

This edition of Simms in the Senate covers Senator Robert Simms' recent work on promoting green jobs for SA, protecting the Great Australian Bight, standing with the community against a nuclear waste dump in regional SA, phasing out live animal export, and the latest campaign news on marriage equality, Safe Schools, tertiary education, and more.

Commenting on tonight's ABC report that shows exported Australian cattle sledgehammered to death, Greens animal welfare spokesperson Senator Lee Rhiannon said:

Commenting on reports that Greyhound Racing NSW has charged 179 trainers and owners for allegedly exporting dogs to Macau, Greens spokesperson for animal welfare Senator Lee Rhiannon said:

"The unwillingness of the Australian government to administer criminal charges against offending export companies means we have seen yet another expose of animal cruelty on TV," said Senator Rhiannon.

US media reports that Australia may have broken Californian lobbying laws in an attempt to overturn the ban on kangaroo products highlights how far the Abbott government will go to benefit a handful of exporters, Greens spokesperson for animal welfare Senator Lee Rhiannon.
