We thought it was a joke – but this roundabout in Sydney’s south-west is real and causing chaos

A diamond-shaped roundabout in Austral, a suburb in Sydney’s south-west, has become the centre of confusion for drivers.

Recent drone footage, featured on the Today Show on Channel 9, reveals motorists struggling to navigate the intersection. Some are forced into multiple-point turns while others, frustrated by the layout, drive straight over the central structure to get through.

This roundabout is located within the Liverpool City Council area and stands out because of its unusual diamond shape. Unlike the standard roundabout, this design is unfamiliar to many drivers and is causing delays, near collisions, and traffic build-up during busy periods. Even the turning circle of a Toyota HiLux can be seen under pressure as drivers attempt to navigate the tight, angular layout.

Liverpool City Council has admitted it is unclear how this design was approved, with an official investigation called to understand the decision-making process behind the roundabout’s construction. Aerial images show that there was ample space for a traditional circular roundabout, which raises further questions about the choice to use the diamond design.

Despite the challenges, there have been no major accidents reported so far. However, local residents and commuters say the roundabout causes ongoing frustration, especially for large trucks and drivers unfamiliar with the area. Many are hoping for improvements to make the intersection safer and easier to navigate.

The council is expected to review the situation and consider potential changes, which will likely include redesigning the roundabout at the taxpayer’s expense.
