The Kings Park club wants to boost its number of pokies from 30 to 35 after buying machine entitlements at auction last May.

But the proposal falls foul of the Brimbank Planning Scheme. A report to last week's planning committee meeting found an increase in machines would be inconsistent with policies requiring the additional machines to provide a benefit to the community.

The club says it uses revenue from the machines to support local sports teams, organise clinics for local schools and hold events and activities for other clubs and groups.

A social and economic impact statement prepared by a consultant suggested the club had made considerable inroads into providing sporting opportunities to the local community.

"It is evident that this is a venue that makes a substantial contribution to the local community," the statement read.

The statement found the five new machines would boost the club's coffers by more than $220,000 in their first year, taking overall expenditure to almost $4.7million.

The council report considered the possible benefits of this increase in earnings to the local area but found these were outweighed by the potential for negative social impacts on an area of high socioeconomic disadvantage.

"The proposal has potential to have a negative impact and fails to adequately identify a net social or economic benefit to the community," it found.

The Victorian Commission for Gambling Regulation will hold a public hearing into the proposal on May 10.
