South Australian Premier Jay Weatherill has travelled to Perth in a bid to secure more mining investment.

Mr Weatherill wants mining companies to look to develop the state's resources and for mining service companies to use the state as a base for their wider operations.

"That's beginning to happen and we believe there is an ideal location here in South Australia to service the whole of the mining industry, not just around Australia, but around the world," he told reporters on Monday.

Mr Weatherill said South Australia was a competitive place to do business and had the skills base to successfully service the mining sector.
