The federal Labor government announced $5.2 million towards the redevelopment in August last year, "regardless of what party won power at the election".

The government approved the regional development works in caretaker mode. 

However it is unlikely the Coalition government will commit funding to the project in this year's budget.

Mr Retallick said the centre had now moved on from its disappointment and had been involved in positive discussions with the current government. 

"We are not expecting a commitment in this Federal Budget and we are comfortable with where it is at," he said. 

"We're as confident as ever that we will receive funding in the not too distant future. We'll keep working at it until we lock it in."

About $7 million is required for the redevelopment to go ahead, with support needed from all levels of government.

Member for Bendigo Lisa Chesters has called for the tennis centre funding to be restored ahead of the budget.

She said it was expected the tennis centre would be funded under the Community Development Grants Program, established to support infrastructure.

The program will fund projects including the 2013 election commitments and some identified uncontracted projects from the Regional Development Australia Fund and Community Infrastructure Grants Program.

A total of $342 million is available.

Federal Sport Minister Peter Dutton has been contacted for comment.
