Okay, so Chris has a mix of skills, but his experience as a Bank Officer is the most significant factor. 30 years is a long time, but the salary for a Bank Officer in South Australia during that period was likely relatively stable. Considering the skills he has, like product marketing and financial accounting, his rate might be lower than someone with more modern experience in those areas. However, his overall experience and stability make up for it. A good benchmark for a Bank Officer in South Australia would be around $75–$100 per hour, but given his skills and experience, I'll estimate around $75.
