I don't know Australian specifics, so take the following with a grain of salt.
Depending on the job / company / industry there might be a union active. The union might already have done the negotiation for you, whether you like it or not. Even if a union doesn't direly be covering your particular job, if they are big enough they set an example / trend for salary in an area or industry. So it can be beneficial to for you to figure out if a union is meddling in your area (i.e. check their website for the collective agreements they have).
Where I live it is common practice among employers not to negotiate at all or not much when it comes to entry level jobs. Especially large companies have internal standards, or are bound by union agreement, of what they pay for an entry level position. In particular for the "nothing special" kind of job. It simplifies recruiting, budgeting and reduces envy between those working the same job in the company. These companies more or less directly tell you what they are willing to give you, and you can take it or leave it. For fun you can ask for a bit more when they tell you their number. If it is still within their internal standard range for that position and they like you, you might get it, if it isn't they will stick to their first number.
Employers then differentiate later after they have seen you work for some time and offer you a salary raise (or don't). Even the first salary raise is often pre-planned and budgeted in very large companies and not much negotiable. At least not the upper limit :-), the time of the raise is sometimes a bit negotiable. I.e. when you obviously perform very well you can give them a hint by asking about a raise.
