Take a look at this article on www.news.com.au which highlights that people with science, technology, engineering or maths (STEM) qualifications - whether from university or a vocational trainer - have a better start than their non-STEM counterparts.
For university graduates, the highest average starting salaries were in dentistry ($77,000), medicine ($62,624), engineering ($62,102), surveying ($60,049) and rehabilitation ($59,603). This compared to a $52,840 average.
Yet another reason why surveying is a great career option.
