The bloom has attracted up to 20,000 admirers who filed past, hoping to experience the smell for themselves, with some attendees describing it as "like death," "like poop," and "like sewage water."

A rare plant known as the corpse flower bloomed in Sydney on Friday for the first time in more than a decade, emitting an odour likened to rotting flesh and delighting thousands who queued for a whiff.

The flower has been said to smell like rotting flesh, wet socks or hot cat food, and only stinks for 24 hours after blooming.
