Okay, let’s tackle this. So Melissa has a degree in horticulture, which is a specialized field. Her experience in landscaping and project management is also valuable. In Australia, horticulture professionals can expect to earn around $40–$60 per hour, depending on the industry and location. Considering her experience and education, I’ll estimate her hourly rate to be around $45, which is at the lower end of the range. This is because her experience is mostly in the public sector, which tends to pay lower rates compared to private sector professionals. Additionally, her degree is in horticulture, which may not be as highly valued as degrees in more general fields like business or engineering.
