Sydney's Taronga Zoo is conducting a full review into "a significant incident" after five lions escaped their enclosure, sparking an emergency lockdown at the iconic tourist attraction.
Zoo executive director Simon Duffy said one adult lion and four cubs were spotted outside their main enclosure at 6:30am Wednesday - but did not get past the second 1.8-metre fence that separates them from the rest of the zoo.
"At no time did the lions exit that area or exit Taronga Zoo," he told reporters.
