Climbing on Australia's iconic Uluru landmark, previously known as Ayers Rock, is to be banned from October 2019.
The board's chairman Sammy Wilson was expected to read a speech during the meeting saying that its Indigenous owners have felt intimidated into keeping Uluru open for climbing.
The traditional owners of Uluru, the Anangu people, have called for the climb to be closed since 1985, when the park was placed in indigenous hands.
The park's Board of Management voted unanimously to approve the change, which has been the subject of lengthy discussion.
Because of an agreement with Australia's tourism industry requiring at least 18 months notice, the Uluru climbing ban will officially start in late October 2019. "This decision is for both Anangu and non-Anangu to feel proud about".
He added: "Closing the climb is not something to feel upset about but a cause for celebration".
"If I travel to another country and there is a sacred site or an area of restricted access, I don't enter or climb it, I respect it. Let's come together; let's close it together".
"This decision has been a very long time coming and our thoughts are with the elders who have longed for this day but are no longer with us to celebrate it", land council director David Ross said.
According to Parks Australia, the climb is the traditional route taken by Mala on their arrival at Uluru, and the path is of great significant to Anangu.
It also warns of the dangers of climbing Uluru, including that many have died while scaling the rock.
The site is often closed to climbers after the death of important indigenous figures as a mark of respect.
