Liberal delegates at this weekend's state conference should stand up against Tony Abbott's assault on Tasmania, the Premier, Lara Giddings, said today.

Ms Giddings said the Federal Opposition leader had outlined a number of policies that would severely impact on jobs and services in Tasmania.

"Mr Abbott's repeated declarations that he supports a per capita based distribution of GST funding, as proposed by mainland Liberal Premiers, would cost Tasmania up to $700 million in annual funding, the equivalent of the cost of 800 doctors, 3000 nurses, 500 allied health professionals and over 100 child protection staff," Ms Giddings said.

"His plans to rip up the NBN would cost Tasmania 800 jobs in the rollout and first mover advantage in the new digital economy.

"His promise to repeal the price on carbon if he is ever elected as Prime Minister, would cost up to $70 million per annum to the State Budget.

"Furthermore, he has sold out the Tasmanian forest industry by refusing to support legislation to ban illegal logging and to restrict the importation of illegally logged timbers into Australia.

"The Tasmanian Liberal Party must stand up against Mr Abbott's anti-Tasmanian agenda, and to urge him to abandon his policies that would severely damage the Tasmanian economy.

"A failure to do so would confirm the Tasmanian Liberal Party, led by Will Hodgman, lacks the backbone to stand up against the bully-boys on the mainland."
