SA to lose under secret GST plans: Labor SOUTH Australia would lose almost $1 billion a year under Opposition leader Tony Abbott's secret GST plans, the state and federal Labor governments say. "Late yesterday it was revealed that Victoria, Queensland, NSW and Western Australia's Liberal Premiers have formed a pact to change the way GST is distributed, a move Tony Abbott thinks makes a lot of sense," said Finance Minister Penny Wong and Mental Health Minister Mark Butler. They cited a comment made by WA premier Colin Barnett in state parliament on Wednesday that "four states' premiers and treasurers have a broad in-principle agreement that the GST should be progressively changed so that most of the money is allocated on a per capita basis." Ms Wong and Mr Butler on Thursday said Mr Abbott would be prepared to stand by and let around $1 billion be taken out of SA's annual state budget, hitting schools, hospitals and essential services. The federal government supported the current GST distribution which helped ensure all Australians have access to the same level of services no matter where they live, they said in a statement. SA premier Jay Weatherill said his WA counterpart had revealed that Mr Abbott has an agreement with the larger states to rip GST revenue from South Australians. The agreement breached the fundamental principle of a fair go for all Australians no matter where they lived, he said in a statement.
