$20 voucher code for new customers from their new "Boogers or Broccolis' Facebook App Quiz @ http://www.facebook.com/AussieFarmersDirect/app_316025495186... but seems to be a generic code that can be used multiple times.
Can be redeemed from their website http://bit.ly/12vzYZr and by clicking "Claim Voucher" up the top right hand corner and typing in the coupon code: NICEWORK.
They do have limited delivery areas but hopefully it comes in handy for those who are looking to try out their products.
UPDATE: For those having issues with the site, or want to know about service areas, try calling them on 1300 645 562 and quote them the Facebook promotion and code!
UPDATE 2: Seems as though different codes are given based on how you submit the quiz. Codes GREATWORK & WELLDONE also works as well (same voucher amount for $20).
UPDATE 3: From the rep:
As per our terms and conditions, 'New Customer' promotion codes cannot be used in conjuction with any other offer, including other codes. Our system will automatically update any customer accounts to remove duplicate codes and therefore any additional credits.
UPDATE 4: It seems as though only the original NICEWORK code now works.
update5: code still valid - changed to arbitrary expiry date
