Nah, raising stuff from the floor without prior notice prevents those not in the know having a voice and a vote. The proper way to deal with floor matters is for members to raise the issues and the meeting can discuss, the board can then take the issue on board for possible resolution. If it is not resolved to the members are entitled to bring the matter back to an AGM or GM with due notice and then the attendees and potential proxies can take an informed decision.
The reason for allowing the corporations law to have an impact on motions at a meeting is that there may be issues under corporation law where a particular resolution must, may or may not be moved or carried. I'm not a great fan of the corporations law as it forced companies and their members into the claws of lawyers and whackjobs at ACCC and ASIC. But on the other hand it attempts to keep everyone honest (but fails miserably in the case of big business and the NSW Club industry). It appears that the behaviour of the RAAus Board was to prevent gaming of the system - NRMA was pretty good at that.
