Full time salaried employee or Independent Contractor?

I work part time ad hoc shifts as a doctor at a private hospital, where I am paid an hourly rate and my hours of work are between 0 and 30 a week. In terms of tax deductions (specifically MPS - medical malpractice insurance, travel expenses, training course fees); would my work be classified "full time salaried work"?

I understand this is important in terms of which items one can claim back.

Are you an Independent Contractor?
