There is a difference between new parliamentarians and public office holders. In both cases, however, my office has always encouraged everyone to ask questions. There is an adviser that all parliamentarians and all public office holders can call at any time to ask questions. In some cases, the questions are addressed to the Conflict of Interest and Ethics Commissioner. I was always available to meet with anyone who wanted to meet with me.
My suggestion is simply to ask questions if you encounter a problem. You can also read the guides, as they contain several guidelines. I would suggest that you ask questions of an adviser; it's quite easy.
