"This isn't the beginning of a big boom - we just need to be cautious." - KPMG analyst Julia Jones
That price helps determine the payout to dairy farmers and is at its highest level since January, but remains below a level of about $US3000 that some farmers need to break even.
All other commodities - except cheddar - made price gains.
Julia Jones, farm enterprise specialist at KPMG, told Morning Report the price increase was cause for cautious optimism.
"There's so much supply out there at the moment, so really we needed to see demand increase, obviously that's what happened."
She said increased demand from Asia would have pushed up prices but this was not a sign of boom times ahead.
"We need to be cautious in the farming sector around price and cost structures on our farms. This isn't the beginning of a big boom - we just need to be cautious."
