Not true. Honours makes you stand out from the run of the mill candidate and definitely pays more.
To the OP: Doing honours is a good idea. Also approach your lecturers; they're often involved with development companies as consultants (or own a company) and could put in a good word for you.
I started doing holiday jobs and temp work in my 2nd year already.
I suspect that kefren's comment probably came from some of the recent surveys:

He makes a good point that once you have enough experience, having just hons vs. just a 3 year degree is not hugely beneficial in SA, which I agree with.
That said, there is definite bias in the way these numbers are represented, which is why I strongly suggest doing honours. There are broadly speaking 3 ways to go once honours is finished:
1) You go into the work force, and get counted against the salary numbers in the survey.
2) You go overseas (Honours is a much stronger qualification by international standards), and you don't get counted in the survey.
3) You do a masters degree, and you get counted in a different bin in the survey (MSc, or eventually PhD).
In general, the better honours students will opt for 2 or 3 (not
always obviously), almost all of the top half of my honours year went either to various big overseas companies or went on to do MSc degrees - the point being that the number represented in the survey is biased towards the bottom of the honours class. Those who went on to do MSc and/or PhD degrees (
and stayed in the country) in general do very well (38% and 69% higher salary respectively according to the survey).
In summary, the honours degree is a great piece of education - opening doors overseas, and for post-graduate education. One big reason a person should do it is to explore these options. If, however, for reasons unrelated to skill that person decides to stop at the honours level
and stay in SA, his/her income will likely be much higher than the honours average in the survey (since the selection bias does not apply to you).
