Domino's Pizza has reported a decline in sales, with the US pizza chain pointing to its Australian operations as a key factor dragging down performance. The company's Australian arm has struggled after implementing a significant change to its business, which appears to have backfired and hurt customer demand rather than boosting it.

The setback in Australia has weighed on Domino's broader financial results, contributing to what the company described as "a drag" on overall performance. The chain, one of the world's largest pizza delivery businesses, has faced ongoing challenges in the Australian market as it works to address the fallout from the change and stabilise sales in the region.
