Video posted to Instagram shows Bambi Le Fist drinking out of the instrument during Australia Day celebrations.
She was wearing a floral bikini and shouted "straya" after finishing. Perth model Cassy Walker filmed the video and quickly faced criticism for the stunt, the Daily Mail reports.
"This is so disrespectful to our culture," one person wrote. "This is wrong on so many levels."
Ms Walker's Instagram is now private and cannot be accessed unless she has given people permission to view it.
