Is Warnbro more a blue collar or professional area?

Blue collar

The beach-side of Warnbro is lovely south of Warnbro Sound Avenue, and I am sure that there is a mix of blue collar and white collar workers there. That part of Warnbro is near the beach and although it is an older part of Warnbro, I would rather buy a home there than on the Ennis Avenue side of Warnbro, which can be very anti-social and feral depending on where your home is situated.

Here's some stats from the 2011 census:

The main occupations of people from Warnbro are Technicians and Trades Workers 21.6%, Labourers 13.1%, Clerical and Administrative Workers 12.9%, Community and Personal Service Workers 11.4%, Professionals 11.1%, Sales Workers 10.1%, Machinery Operators And Drivers 9.7%, Managers 8.6%.
