There has been some information about intervention orders on the Judicial College website for a while.
There is a 12-page overview, a summary of important provisions, and some checklists. These have been around since the legislation was overhauled 3 years ago and are useful for practitioners trying to get to grips with the system.
Recently the College uploaded a Family Violence Bench Book. It doesn't have the same depth or range as previous Bench Books (case law in this area is rarer), but no doubt the resource will develop over time. Perhaps it's the first installment of the Magistrates' Court Bench Book I am still waiting for.
There's also a link on the JCV site to Magistrate Peter Power's research on family violence and stalking orders, which is impressively detailed.
