South Australian Premier Steven Marshall has unveiled a plan to make Adelaide "the most liveable city in the world" β promising a 350-hectare "water oasis" in Adelaide's north-east and a rejuvenation of the River Torrens if he is re-elected.
Key points:
- The Liberals have pledged to improve the health of the River Torrens
- The Premier and his party are both down in the latest polls compared with Labor
- The opposition has promised more money for community mental health services
Starting with a $27.5 million "nature boulevard", Mr Marshall said his government would improve water quality and amenities along the entirety of the Torrens, from the Adelaide Hills to the coast.
"This once-in-a-generation upgrade of the River Torrens and Linear Park trail will stretch from the north-eastern suburbs right down to the beach for families, cyclists and walkers to enjoy," he said.
"The River Torrens is an iconic waterway and we want to transform it into a tourist hotspot."
Environment Minister David Speirs said the government would also develop wetlands to filter pollutants,
reintroduce native species like the platypus and even encourage recreational fishing.
Almost a third of the project's funding will come from the federal government and local councils.

The Crystal Lake Recreation Park β which is yet to be costed β would include cycling paths, walking trails, a beach and picnic area, kayaking facilities and swimming amenities.
The Premier spruiked the announcements as an "unprecedented opportunity" to grow the state's visitor economy and create jobs.
"Adelaide has already been recognised as
the third most liveable city in the world β¦ and projects like this will only enhance this reputation further," Mr Marshall said.
"My goal is for South Australia to become the most liveable city in the world."

While Mr Marshall was talking up his latest election promises, he was keen to talk down the results of a new poll.
The Newspoll, published in The Weekend Australian today, placed Opposition Leader Peter Malinauskas as preferred premier by a margin of 7 per cent (46 to 39).
