> There are two types of preservation notices—domestic (‘which cover stored communications that might relate either to a contravention of certain Australian laws or to security’) and foreign (‘which cover stored communications that might relate to a contravention of certain foreign laws’).

> In turn, there are two types of domestic preservation notices—historic (‘which cover stored communications held by the carrier on a particular day’) and ongoing (‘which cover stored communications held by the carrier in a particular 30-day period’).
