Friends and family of Rebecca Mackenzie are pleading for public assistance to find the missing Brisbane woman.

Ms Mackenzie, 22, was last seen celebrating a friend’s 23rd birthday at Met nightclub in Fortiture Valley, in Brisbane’s nightclub precinct.

She got into an argument with her boyfriend at around 2:00am on Sunday and her belongings were left with a friend before she “stormed out”.

She has not been seen since.

The hashtag #findbec is trending in Brisbane as locals and Ms Mackenzie’s friends try to spread the word of the young woman’s disappearance.
