What roof slate material would be available nearest to Sydney?
A19: The old quarry at Goulburn is the closest (and only) location to Sydney containing material even vaguely comparable to the imported Welsh roofing slates, but the quality is relatively poor and very variable and there was always a lot of wastage. There are no other places that I know of that were worked for roofing slates, although Mudgee is a well known source of flagging stone slate.
