Tasmanian Labor has proposed restructuring the government businesses involved with the bungled Spirit of Tasmania vessel replacement program, bringing one under more direct government control.In his state budget reply speech, Labor Leader Josh Willie proposed "structural reform to clean up the Spirits mess", and "end the TT-Line bailout cycle".Last week's state budget contained a $506 million equity injection over four years for state-owned ferry operator TT-Line, to help it deal with the financial fallout of the vessel replacement program.It followed a $75 million equity injection in last year's budget.The botched project has seen the ships, which were complete years before the necessary berthing facilities, delayed from entering service by years.It has also run $717 million more than expected, mostly due to cost blowouts on berthing facilities.Josh Willie says Bass Strait is "part of our national highway — and it should be funded like it". (ABC News: Ebony ten Broeke)Mr Willie said TasPorts would "cease to exist as a government business enterprise" under a Labor government, and instead be reclassified as a "dedicated transport infrastructure entity".That yet-to-be-named entity would then take ownership of TT-Line's vessels, berthing facilities, gantries and terminals, as well as its estimated debt of $1 billion.Under the plan, a debt-free TT-line would then lease the ships back."So that TT-Line can focus on what it does best — running a reliable Bass Strait service," Mr Willie said.He said this would end the need for further bailouts, while still retaining "full ownership and operational control"."This is about fixing the structure and reducing risk."The Labor leader argued this would also allow the state to better argue for a "Commonwealth Sea Highway Funding Agreement" to help equalise transport costs.He argued the commonwealth should be funding infrastructure like vessels, berths and terminals."Bass Strait is part of our national highway — and it should be funded like it," he said.The construction of the deeper Berth 3 facility for the Spirit of Tasmania ships is underway in Devonport.

Which services? Which hospitals? Which schools? Which child safety supports? Which community programs?" he asked."Patients are waiting too long, ambulances are coming too slowly, nurses are exhausted, hospitals are buckling under demand, and now this government is cutting more than $700 million from health."In question time this morning, Health Minister Bridget Archer faced stiff questioning on the "operational efficiencies".Despite the Health Department being asked to find $702 million in savings, she has maintained, "there are no cuts in health".
