A woman has fronted court accused of sending death threats to NSW Premier Chris Minns.

Sienna-Rose Caprari Corby, a 27-year-old from Balmain, was charged in August with three offences, including using a carriage service to threaten to kill and threaten serious harm.

Police said at the time the alleged death threats were sent over social media.

It's alleged the threats were a series of escalating violent messages sent to Minns' official Instagram account, and were related to the premier's position on the March for Humanity protest over the Harbour Bridge last month.

Corby is yet to enter a plea to the charges.

She remains on bail, and is set to front court again later this month.
