The region's fishers have been encouraged to get their applications in for the NSW Government's Habitat Action Grant program.
The deadline for the program was extended until October 16.
Hawkesbury MP Robyn Preston said that recreational fishing groups, Landcare organisations, high schools and local councils in the Hawkesbury area would all be able to submit a funding application to see their native fish habitats flourish.
"This is a fantastic grants program that I hope all anglers in the Hawkesbury region can take full advantage of," Ms Preston said.
"Our waterways here, and right across the state, are already among the most beautiful in the world, but this is a chance to make them even better.
"Projects funded through the Habitat Action Grants could include rehabilitation of river banks or wetlands, re-snagging waterways, reintroducing native vegetation or modifying barriers for fish to passage."
Habitat Action Grants are funded from the Recreational Fishing Trusts, where all funds raised by the NSW Recreational Fishing Fee are placed.
