Not sure about Woodcroft but a lot of the neighbouring suburbs are dodgy (Doonside, Mt Druit etc)
woodcroft is a pretty nice area tbh. It has its own little shopping centre with a maccas and its pretty secluded, although it is pretty close to doonside. Still it is a much better area that doonside and mt druitt. Its just off Richmond Rd close to Blacktown - I live in Hassall Grove which is off Richmond Rd as well but closer towards Marsden Park/Richmond.
I live in erskine park, closeish to those areas. Really it depends, i live in a good area close to mt druitt, woodcroft may be a good area close to a bad one (doonside)
