Prime Minister Scott Morrison on Monday announced the proposed Marinus Link energy cable between Tasmania and Victoria was one of 15 major projects set to be fast tracked, with assessment and approval periods dropping from an average of 3.5 years to 21 months.

He estimated the fast tracked projects would create more than 66,000 jobs nationally, and would bring the jobs "to the market" earlier.

Also featuring new renewable energy projects, including wind farms and pumped hydro, the Tasmanian energy strategy is expected to create thousands of jobs and billions of dollars of investment in Tasmania, as well as a large new income stream from energy exports.

Mr Morrison said the pandemic had caused the greatest economic shock since the Great Depression.

He described the situation as a health and economic crisis.

"We are saving lives and we are saving livelihoods," he said.

"We've managed to better than our peers, and even our hopes."

He said economic recovery was now the main focus of the national cabinet.

"We are now coming back," he said.
