members. Local Government, State lower house and House of Representatives candidates are preselected by a ballot of members residing only within those electorate, while state upper house lead candidates are decided by a ballot of all party members residing in the respective electoral region. Federal Senate lead candidates are decided by a ballot of members across the whole state. Working groups A variety of working groups have been established by the State Council, which are directly accessible to all Greens members. Working groups perform an advisory function by developing policy, conducted issues-based campaigns, or by performing other tasks assigned by the State Council. These include: Victorian Young Greens Green Women's Network Queer Greens Victoria Multicultural Greens Victoria Country Greens Victoria Electoral results State elections Three Greens representatives were elected to the Victorian Legislative Council at the 2006 state election. Greg Barber won a seat in the Northern Metropolitan Region, Colleen Hartland won a seat in the Western Metropolitan Region after a recount, and Sue Pennicuik won a seat in the Southern Metropolitan Region. Minor parties have had little or no success in state lower houses that have single-member electorates, though in other states where there are multiple-member electorates in the lower house (such as Tasmania's or the ACT's), or where there are multiple-member electorate/s in the upper house (such as in NSW, SA and WA), minor parties including the Greens have been more successful.

In the Legislative Assembly , Greens candidates were second in four two-party-preferred races in inner-city seats at the 2002 and 2006 state elections, three of which are now marginal seats (that is, they require less than a 5% swing to change hands). Richard Di Natale came within 2% of winning Melbourne from Labor cabinet minister Bronwyn Pike in 2002 and 2006. The 2010 State elections saw another increase in the Greens vote - a 1.2% swing to give a primary vote of 11.21% with all three MLCs re-elected.
