WE'RE missing a sister, not an apostle.

A limestone rock stack that crashed into the sea off Victoria's west coast on Friday is not one of Twelve Apostles as originally thought but part of a rock formation called the Three Sisters.

A limestone rock stack that crashed into the sea off Victoria's west coast on Friday is not one of Twelve Apostles as originally thought but part of a rock formation called the Three Sisters.

Parks Victoria had reported that the crumbled rock on the iconic coastline was one of the eight remaining famous formations found along the Great Ocean Road.

On Sunday a further study revealed the stack collapse was actually the smallest member of the Three Sisters, which can be seen on a lookout platform nearby at the Razorback Lookout at Loch Ard.

Parks Victoria says it's received many calls about the fallen rock off the Port Campbell coast.

”The collapse is a reflection of the changing coastline,” Parks Victoria says.

”Erosion is a significant issue in the area and creates the striking features for which this limestone coastline is known.”

While the revelation is a relief to those who love the 45-metre tall Apostle formations - who now sit as eight remaining instead of seven - it comes while Parks staff are trying to confirm another stack collapse.

Stormy weather has prevented staff from investigating further if a second rock crumbled as feared over the weekend.

The recent changes to the area follow the crumbling of the Island Archway, which fell into the sea on June 11.

Parks Victoria was quick to point out that the coastline will “remain spectacular” despite the recent crumbling of their main tourist attractions.
