There are new mini electric cars for the under-7s and for older children there are cars from the former Hamilton Daytona Park.
"We still have the original go-karts as well because parents have fond memories of riding in them and they are still in good condition."
The Wilsons' dog "Rocky the Riverland mascot" has become another attraction at the park, making friends with visitors and passers-by.
"He will go off for walks with people who are going by with their dogs," said Mrs Wilson.
"People are happy for him to tag along and they drop him off on their way back."
The park has been open for shorter hours during winter but Mr Wilson said they will extend the hours on Monday.
The park will be open from 10am until 5pm and Mr Wilson said people who can't get there can still contribute to the relief fund and he thinks it will be great if local businesses and support it as well.
Anyone wishing to support the fund can contact Mr Wilson at riverlandfamilypark@gmail.com.
