Promises made by politicians leading up to elections are often taken with a grain of salt.

But recent history shows Keira MP Ryan Park has long supported the campaign to revitalise Corrimal.

That's why Corrimal Chamber of Commerce president Paul Boultwood was happy to be on hand when Mr Park announced that should Labor win government on March 28, it would set aside more than $3 million to revitalise the Corrimal CBD.

Mr Boultwood has often told the Advertiser that the Keira MP had played a big part in helping Corrimal secure funding for projects.

But the chamber president said Corrimal was crying out for more money to help revitalise the "often neglected" northern suburb.

Mr Park said the revitalisation project had been on the drawing board for some time.

"I know just how important it is to the local business community and residents in the most populated suburb in the northern Illawarra," he said.

Mr Park said the chamber, led by Mr Boultwood, had done a good job making sure all political parties were aware of the need to upgrade Corrimal's business district.

"Mr Boultwood and local small business owners have been tireless campaigners for the revitalisation of the area."

The funds were part of the already announced $15 million Main Street Improvement Fund - a key component of Labor's $380 million Illawarra Infrastructure Investment Fund.

Under the plan, funding will be allocated to Wollongong City Council, which will also be expected to contribute. The money will be used to upgrade seating, footpaths, lighting, signage and enhance the precinct.
