A $2.3 million property omission in his parliamentary records has landed Labor frontbencher David Feeney in hot water.

Mr Feeney, who is in a tight battle with a Greens candidate over his inner Melbourne seat of Batman, says the purchase of the negatively geared house in Northcote is on the public record but he omitted to register it.

"I have today written to the register of members interests seeking to rectify my register so that the property is properly found therein," Mr Feeney told ABC radio.

The Greens have seized on the admission, with Adam Bandt questioning what will happen next.

"Australia lost a premier over a bottle of wine," Mr Bandt told ABC radio, referring to the resignation of former NSW premier Barry O'Farrell.

"What happens to someone who doesn't declare a $2.3 million property?"
