The carport was $1850. It is 6m x 6m double carport with gable roof in colorbond, so it is one of the nicer ones. It came with everything needed (except decent instructions!). In our area, we didn't need a council permit for it as it's freestanding, although we did consult with the council, submitted the plans for it (that were provided in detail by the carport company) and they have noted a permit exemption, so when we come to sell the house, the buyers solicitor will see that it's all ok.
We bought it from Shed Bonanza in Melbourne, cost us $160 delivery to have it sent here, and takes about 3-4 weeks. The best quote locally was $3000!
