Shannons all the way. By calling them you will find a number of things out and the employees are actually interested in the car. E.g On the website, they dont insure under 25 yet my g/f has had insurance with them in her own name since 23. I don't believe the website accomodates for shared basement garages (apartment ones) yet as long as it is locked and security gated, they are happy with it.
Definately give them a call though. The only problem I had, at the end of my first year, the premium went up by $200 and I am Rating 1 protected with no claims. They put it down to the car and other claims in my postcode but wouldnt budge on price, even though I told them I would take all my business elsewhere. I also have my house contents insurance with so get a multi policy discount. They were much cheaper than RACV so managed to offset the cost increase on the car with the contents.
