The Lockyer Valley Regional Council have voted to postpone any decision to suspend activity at the Laidley Racehorse Saleyards despite animal welfare concerns.

The RSPCA and Biosecurity Queensland have launched an investigation into the saleyards after receiving multiple reports animals were left without water or shade during the sales held on December 30.

The council said it is looking at all possible options, including suspension, but will hold off any decision until they speak with management tomorrow.
