A report to councillors at Monday night's meeting stated that the anticipated difference between the project budget and the stadium construction cost was $130,678.

Cr Dallas Tout said credit should be given to staff for having the stadium "open, under budget and with no injuries" after a multi-year process.

"This has been a long, long road with multiple funding avenues and discussions," he said.

"To get where it is now and under budget, and the most important part is the 482 on-site inductions and 33,490 hours worked without injury."

The stadium was officially opened last month after being under construction since October 2017.

Staff have proposed that the unused funds will go towards improving the stadium further such as additional internal security cameras, floor protection for furniture, a baby change table and irrigation and tree planting.

Councillors have approved the next step towards a $6.1 million Farrer Road widening and reconstruction project.

The Riverina Anglican College has an entrance off the road and the Calvary Community Care Riverina aged care residence is nearby.

College principal Paul Humble said the proposed project was "wonderful".

"The project will benefit not just The Riverina Anglican College but the communities of Estella and Boorooma as well," he said.

The council will proceed with acquiring land access while beginning road works.
