Hi,
Welcome to the board.
It is pretty meaningless comparing quotes from different people, as it depends so much on suburb, no claim bonus etc.
Most of the companies have web sites that let you get a firm quote online, allowing you to input your particular circumstances and compare 4-5 companies in 30 minutes. It is definitely worth doing that, as conditions vary. For instance for me NRMA was cheapest, but for someone in the next suburb with a different rating they may well be the most expensive.
Also, it is worth getting a quote from the BMW insurance company through the dealer. In my experience they are usually pretty competative.
For what it is worth my insurance is NRMA $1150. That will seem expensive to someone living in the bush, or Brisbane or Perth, but will seem ridiculously cheap for some people living in high risk suburbs in Sydney.
Good luck
Robbo
