Independent Frome MP Geoff Brock has called for an inquiry into mining land access.
He says his Bill would clarify the state government's controversial Mining Bill.
He launched a move in parliament to set up a commission of inquiry into land access regimes under the Mining Act and the Opal Mining Act and the operation of the energy and mining department.
The notice of motion was seconded by Independent Member Troy Bell,
Mr Brock said the government's Mining Bill was causing division and concern.
"There is support for my move from peak industry bodies including the Grain Producers SA and the South Australian Chamber of Mines and Energy who jointly called for an independent review into mining legislation earlier this year," he said.
"It was agreed at the time that a review should ... look at best practice land access frameworks in New South Wales, Queensland and Western Australia and I believe this is a critical way forward for South Australia.
"It is essential that we protect our farmers and their industry and listen to their concerns about the lack of protection of arable land which is reducing every year."
Under the Mining Bill, exploration would be allowed closer to homesteads - within 200 metres rather than 400 metres and landowners would face fines for obstructing access.
Mr Brock said he was giving notice that he was introducing his Bill for an Inquiry into land access regimes at the end of this month.
