Many tweeps were concerned by the revelations:
#4corners report scaring the living daylights out of me! Wow.

@4corners is melting my brain this evening. If Westfield didn't scare me before, it does now. I want to go back to pens and paper. #4corners

Apparently three Westfield Shopping Centres already have smart phone tracking ready to go. It is similar to RetailNext, instore analytics used in the United States.
This #4corners is A-mazing. This RetailNext stuff in particular. In store analytics. Customer heatmaps & face tracking via security cams.

Simon Johnson was one of many who think that there was nothing new in the episode:
Watching #4corners – none of these issues re US spying, apps used by kids, or Police car tracking are new. Need a detailed follow up story.

There was also plenty of humorous reaction:
I'm happy to check everyone's security in the @4corners audience tonight for FREE. Just tweet me your netbank details #4corners

#4corners my Mum just realised how untraceable she is. She has no phone, car, email address, credit card or social media account!

Just for the record those porn sites I visited were part of a proposed Phd "Digital Sexuality & Cyber Dystopia" #honest #4corners

There were also the inevitable political concerns:
switch over to ABC's #4corners and see why we should've put @WikiLeaksParty & @piratepartyau in the Senate. Big Brother is watching…

"…no way a govt can collect that volume of data and remain incorruptible…& when you've got it, you'll find a use for it"… #4corners

Concerns that big brother is secretly mining our big data are bound to increase with growing public awareness. However not everyone is that worried:
I'm happy for companies to use my data if it's not done maliciously. It would make a lot of things, like shopping, much easier. #4corners
