I'm not sure what the minimum period is officially but in general six months is a practical minimum - from the time a Writ of Election is issued the interval to the actual election is 60 days, and we seem to prefer spring or autumn elections. Typical turnout is hard to predict - if there's nothing contentious going on it can be as little as 30% but when there's a lot at stake then 60% or more is common.
