Payment updates within the Pre-election Economic and Fiscal Outlook show 15 projects have been awarded Community Development Grants since the March budget, with eight grants allocated to marginal electorates.

The total amount allocated across the additional projects since the budget sits at $116.6 million.

Six of the electorates are marginal seats held by Labor, and are being targeted by the Coalition as potential gains. The community grants are allocated at the discretion of the relevant minister, with the PEFO update signalling a pork-barrel fight within seats which could determine whether the Coalition retains or Labor gains government.

Community Development Grants are the responsibility of the Department of Infrastructure, Transport, Regional Development and Communications.

The responsible ministers who have the discretionary power to allocate grants include Deputy Prime Minister Barnaby Joyce and Communications Minister Paul Fletcher.

Payments made since the budget reveal a $15 million grant was awarded for the redevelopment of the Frankston Basketball Stadium, located in the Victorian electorate of Dunkley. The seat is held by Labor's Peta Murphy on a margin of 2.7 per cent.

A further $5 million has been set aside for Scheyville Veteran Wellbeing Centre in the seat of Macquarie, which is held by Labor MP Susan Templeman and is the most marginal electorate in the country.

The Morrison government has been plagued by a number of pork-barrelling scandals associated with grant schemes, including the allocation of money in its commuter car park and sporting grant programs.

The rorting of taxpayer funds has fuelled calls for the establishment of a federal integrity commission to stamp out corruption within the Commonwealth.

Funds through the community grants scheme have also been allocated to the redevelopment of Mount Waverley Reserve for $4 million. The seat is held by Liberal MP Gladys Liu on a margin of 0.6 per cent.

At least three of the 15 projects were Labor announcements that were matched by the Coalition ahead of the election being called.
