Graeme Taylor, who was installed as president last month, intends to maintain the association's proactivity, which often extends beyond the Beaconsfield postcode.

He says the secret to the group is its "energetic" eight-member committee.

This year, the association's vice-president Angelo D'Amelio set up a bulk-buy scheme for cheaper energy bills in Casey-Cardinia and petitioned for extra lanes on the Hallam Bypass.

"As a person who uses the Monash Freeway most days, we've got to get an extra lane to ease the traffic flow," Mr Taylor said.

"Everyone is sitting up and listening. You don't hear anyone disagreeing and it's more than just Beaconsfield. It affects Officer, Pakenham, Narre Warren - it covers a fairly large area of the population."

That's just one issue linked with the growing pains of the south-east growth corridor.

The association also supports a diamond interchange linking Princes Highway and the freeway, south of Beaconsfield, and more car parking at the town's railway station and business district.

Given the intensive population growth, Mr Taylor is surprised Cardinia Shire Council is proposing moving the township out of the growth corridor-based Central Ward to a ward comprising Emerald, Gembrook and Cockatoo.

"I don't think there is a perfect synergy between us and the Ranges Ward."

Meanwhile, 600 residents and businesses have signed up to the bulk-buy energy scheme, with more expected after Cardinia Shire endorsed the plan. The scheme has gone to energy providers for tender.

The group keeps its community posted with a 40-page newsletter every two months, and runs a public forum every third Tuesday of the month.

Mr Taylor has been active in the town since moving there in 1983.

His achievements include helping to set up the town's only bank at the time, a Bendigo community bank in 2009. It has since attracted a rival. He's also proud of the association's beautification of the town's once-dilapidated gateway.

Mr Taylor has scaled back his work as a chartered accountant but his community work still leaves him with little spare time.

"It is fulfilling to see things get done, though I admit at other times it's frustrating and people don't understand how much work is involved."
