Sydney- Suburbs

[MercuryT]

Hi guys and girls.
My Ex (after wife, we legit happy and still friends) I'm really worried about as got into Ice etc - no excuse but her upbringing not great.

She's now suddenly moved to "Schofield" in Sydney. Like overnight almost.

She refuses to answer what her job is (yes I'm not stupid) but seems happy - should I be worried? (yes I have feelings for her well-being unlike my ex-wife)

Is it an OK place?
