The car park and boat ramp upgrade has $1.17 million allocated to it. Transport officials said site work would start today to improve the parking layout.
Acting coastal infrastructure general manager Donna West said the car park work should be finished by late June, then they hoped to upgrade the boat ramp by October.
Ms West said a 50m long floating finger jetty would be installed, which would enable three boats to park on either side, and the existing jetty removed.

"What is being proposed is largely cosmetic."
