It will be almost three years before police officers will occupy their new $18m station at Naracoorte.
Police Minister Stephen Mullighan said work was about to begin at the Smith Street site and it would have a floor area of 750 square metres.
Mr Mullighan said the station would be completed at the end of 2027 and the transfer process would then begin.
The minister was speaking in the House of Assembly on Tuesday in response to a query from Member for MacKillop Nick McBride.
