DAVID and Tina Faust are passionate about the Whitsunday region and healthy living but it wasn't until a problem with buffalo fly in their herd that the couple turned to biodynamic farming practices.

David said he was reading the instructions on an insecticide product when hewas struck by the skull-and-crossbones warning.

"On the bottle it said don't eat the product for 40 days after application," he said.

David began asking himself - do we really want to be doing this?

It was following this epiphany that David and Tina gathered anything that wasn't natural on their farm just outside Proserpine and threw it in the bin.

Since then the DK Faust 106 brand has used all natural feed and pest control and included biodynamic practices in everything they do on their parcel of leased land in Proserpine.

Don Cameron and Karen Rix, of Master Butchers Whitsunday, got together with Tina and David to work out a way the butcher could sell locally produced beef in their two Cannonvale stores.

"Eventually Karen and Don visited our little farm and they were hooked," David said.

Already Master Butchers Whitsunday has taken delivery of 22  animals and are expected to receive another consignment today.

Word is spreading like wildfire and customers are asking for the DK Faust 106 brand by name.

"We are really happy. Once we stopped using the chemical we wanted something more than sending them on the boat would give to us," Tina said.

"People are coming into Master Butchers Whitsunday and asking, 'Have you got DK Faust 106 beef in stock?'

"The story is getting out there and we are very happy."

The couple is now trying to build a network of young cattle suppliers to provide them with healthy, low-stress cattle.
