Labor's Jennifer Kanis has spoken out against an east-west road tunnel, saying it would bring more cars into the CBD.
Her claim comes after Federal Opposition Leader Tony Abbott announced that if elected he would commit $1.5 billion to kick-start an east-west link to connect the Eastern Freeway with the western suburbs.
Ms Kanis said the tunnel, proposed by the Baillieu government, would bring more cars into the inner city and wouldn't solve the traffic problem.
The Greens' Cathy Oke said her party had a history of opposing the tunnel at all levels of government.
"What Melbourne needs is investment in public transport, not a new tunnel or tollway," she said.
Smear campaign denied
Gambling reform candidate Stephen Mayne has made a formal complaint to the Victorian Electoral Commission about the distribution of an anonymous smear sheet.
Mr Mayne discovered a two-page smear letter had been sent to Melbourne voters last week.
The letter attacks his decision to direct preferences to the Greens over Labor and highlights comments that paint a negative picture of his time on Manningham Council, published in a recent Sunday Age story.
Labor Party state secretary Noah Carroll condemned the letter, saying his party had nothing to do with the smear tactics.
Labor preferences
Independent candidate David Nolte, who is also a Liberal Party member, will direct preferences to Labor ahead of the Greens.
In a field with no formal Liberal candidate, Mr Nolte believes his preferences will be "crucial".
Greens launch campaign
Planning policies aimed at empowering residents and local councils were the centrepiece of Cathy Oke's campaign launch last weekend.
Ms Oke launched her campaign with federal MP Adam Bandt (pictured) and Victorian Greens leader Greg Barber at Revolt in Kensington on Sunday.
She unveiled a plan to work with the state government and Melbourne City Council to bolster the rights of residents and businesses in Melbourne's capital city zone.
Ms Oke said city zone residents and business owners "should have the right to appeal, object or even just be notified" about relevant planning applications.
