Rayner accepted the offending was aggravated by the fact a public servant was the target of his client's wrath.
However, he pointed to a "very articulate" letter of remorse written by Holkenbrink which recognised the wide-reaching consequences of her conduct.
Judge Michael Crosbie highlighted the fact the defendant had significant personal issues that served as a trigger for the offending.
Holkenbrink was sentenced to four months' community detention and 15 months' intensive supervision.
