Under the Emergency Management Act 2004 (SA) a person who is absent from employment on official duties in connection with response or recovery operations undertaken in accordance with the Act, is not liable to be dismissed or prejudiced in employment because of that absence [s 33].

If you are a CFS volunteer or similar and are involved in official emergency response duties, you should let your employer know. It might also be that there is a specific enterprise agreement clause or clause in your employment contract which covers whether or not you are allowed to have paid leave when you undertake these official duties.
