I do BBA Bec
I think the advice someone said in an earlier post is very usefull...
What is it that you want to do with your economics degree?
Broadly speaking there are three main areas you can go with economics.
You can take a policy approach, and become interested in economic policy, and all things political...
You can take a very financial approach, and work for the rba (honours required) or in the private sector as a financial economist / analyst
Or, you can do down the business path and be a business development manager, or something like that.

So the question goes - how do you know where you would like to head?
If you like economics at school because you are interested in the policies, microeconomic reform etc etc, then you are a policy buff. BBA Bec is probably not the best thing to do. BBA is very business orientated. Its a bachelor of arts for business students. So you do some marketing, some management, some accounting, some finance etc. You only ever touch policy related issues in the economics side of the degree. For those interested in policy, combining an economics degree with something political is good. So perhaps liberal studies, or even law if you get the marks.
If you do 3 or 4 unit maths, and have a good grasp of numbers, and think that finance might interest you, then you are a finance buff. You probably dont want to do BBA because more than half the subjects are full of pseudo science based psychology shit that just wont stimulate you in an analytical sense. If you want to do a double degree, then you want to do something like economics and applied finance or something.
And finally if you dont necessarily want to become a full on economist, but you are one of those students that wants to go into "business" without really knowing what it is they want to do in business - then the BBA Bec is for you. You do every single discipline of business in your BBA degree, so you have a good understanding of everything in business. Very important for those who want to be managers. On the other hand, having an economics degree provides more integrity to your business degree as you also have specialist knowledge.

Whilst you havent probably had enough time to know which one suits you, as u dont know what uni economics is like - dont worry. You can change degrees. Macquarie is a good uni. Dont buy into this whole concept of Sydney being better and more prestigious. All of the "trendies" that engulf that campus would have you believe it is, but there is nothing that an employer will look at, to prefer a sydney student from an employment perspective. My advice is this. If macquarie university is convinient for you (as it is for me - a 20 min drive to uni and back is priceless considering the hassle that everyone else I know has to do) then come to Mac.
The only way I would specifically recommend Sydney, is if you are interested in policy, and possibly with the intention of doing something political as they offer a better array of courses and subjects aimed towards political science etc.
