Ok, so she needs to get some high-level advice on board. This is probably going to require a few phone calls, explaining the situation, etc, so if she's still having issues with trauma/anxiety she might appreciate someone helping her, maybe by sitting with her and making the calls on speakerphone or something like that. So maybe encourage her to get someone (a friend, counsellor, whatever) to help her work through this.

The sorts of organisations that could give her some advice are places like her union (if she's a member this should be the first place she rings, if she's not a member they might be able to give her some general advice); victim's of crime support organisation; women's information and referral centre; or a workers advocacy/information centre. Sorry I don't know what state you're in, but there are these sorts of places in every state and territory, you can usually find them in the front bit of the white pages phone book.

As to the actual insurance, I have no idea. Some states have victims of crime compensation funds, which might turn out to be the way to claim if none of the other insurances cover this situation.

That employer needs a rocket up their bum. Not following this up is not good enough. Even IF they are not required to claim for these losses through their own insurance, they should at the very minimum be providing some information about the support mechanisms that are in place. Especially given that she is very obviously still traumatised.
