The New South Wales Labor Party investigation completed by barrister John Whelan said allegations of misuse of public money should be referred to the Independent Parliamentary Expenses Authority.
It noted Ms Husar has already referred herself to the authority when the complaints emerged.
The report said allegations of sexual harassment and lewd conduct were on the balance of probabilities not supported.
Mr Whelan’s report found merit to some of the complaints against Ms Husar but said based on the assessment there is not basis for her to resign from Parliament.
The report found that there was merit to complaints that staff performed non-work-related and personal duties for Ms Husar and said that should be referred to the Finance Department, which employs her staff.
It also found a significant difference between the way Ms Husar said she managed her staff and the way the complainants perceived they had been treated — those complainants alleged they found much of Ms Husar’s management “offensive and unreasonable”.
In that regard, the report said after considering both sides, it generally favoured the complainant’s version.
Mr Whelan’s assessment said the leaking of some of the complaints was “reprehensible” and had potentially made tensions worse, “in an environment in which many have reported the stress this matter has placed on their mental health”
