The Tamar River will be cleaned up if promised upgrades to major infrastructure and catchment projects along the estuary and upstream go ahead.
Prime Minister Malcolm Turnbull will announce the $94.6 million fix in Launceston on Friday, which will need to be jointly funded by the state and federal governments.
It comes after a report from the Tamar Estuary Management Taskforce, released on Thursday, made 12 project recommendations to clean up the river.
The taskforce was established under the Launceston City Deal framework.
Mr Turnbull said the federal government would partner with a re-elected Liberal state government to complete the comprehensive list of actions identified by the taskforce.
“The partnership will enable 12 projects to be undertaken along the Tamar Estuary… and will receive equal funding from the state and Commonwealth,” he said.
Premier Will Hodgman said work would be undertaken over a period of five years from 2019.
