The owner of the long-closed Ginninderra Falls says she is "busting" to get the site open again and thinks the time frame proposed by the developer of the massive cross-border development Ginninderry is too long.
Mrs Hyles said she felt public pressure to open the "beautiful site" in Yass Valley and that it should not take up to a decade to make it publicly accessible.
Ginninderry would provide the only access to the falls from the ACT and the developer, Riverview Projects, has offered to provide funding for new fencing, walking tracks and picnic areas within the falls.
Riverview conservation adviser Jason Cummings estimates five to ten-years to fix the visitor infrastructure that's degraded since the falls closed in 2004.
Both the Hyles family and Riverview Projects are waiting to see if Yass Valley Council decides to rezone the land adjacent to the falls for residential development.
Mrs Hyles said if and when that rezoning was approved her family would look at all possible options to reopen the falls sooner than later.
She said she was open to negotiating a sale or lease of the site with Riverview Projects but still wanted to see the ten-year time frame reduced.
