Westpac Bank economist Nathan Penny described dairy prices as "taking a breather" in last night's auction.
The fall is the first since the October 2 auction, and overall, dairy prices had risen by 27 per cent since May.
Penny said the effects of the northern drought continued to linger. "Coupled with improving Asian growth, particularly in China, we expect this will support dairy prices over the remainder of 2012 and into 2013."
