Twitter users immediately mocked the interview.
"What an absolutely glorious train wreck of an interview,"wrote one.
"Brandis has no idea what he's talking about on data retention,"said another.
"Complete car crash interview with Brandis and @David_Speers[on] @SkyNewsAust as he tries to explain metadata,"said yet another.
Steve Dalby,the chief regulatory officer at iiNet,an internet provider that is against the government’s data retention proposal,called the interview"as clear as mud".
He's called on the government to release exactly what data they are after under the data retention proposal before it is legislated later this year.
The government did not have the best day in selling the proposal on Wednesday,with contradictory statements and broken metaphors used to explain the issue.
When describing that"web addresses"would be captured,it's possible Senator Brands meant to say that the IP addresses of web servers people accessed would be stored.
When a web user visits Google,for instance,the IP address left behind as metadata is 74.125.237.198. When visiting Sky News,it's 101.167.166.43.
But if a law enforcement agency accessed this IP address metadata and put it into a web browser they would then be able to determine that the user went to Google or Sky.
Law enforcement or intelligence officials would also be able to determine the duration of time a user spent on the sites,the date they visited them,and the location of the device they visited the sites on.
The same applies to some other sites,but not all. In many smaller website hosting environments for instance,a single IP address might service hundreds of completely different and independent websites. This means that an IP cannot be considered a full web browsing history.
Mr Dalby told Fairfax Media on Wednesday evening that storing IP addresses was very similar to storing web browsing histories.
"[Law enforcement agencies] only have to type the damn IP address[into a web browser] and they'll get the website[you were looking at and] they'll get all the content on it,"Mr Dalby said.
"It's just as invasive as standing with a video camera over my shoulder while I'm browsing and of course that’s what they want,"Mr Dalby said.
Mr Abbott's recently appointed Human Rights Commissioner,Tim Wilson,is also against data retention,as are a number of other civil liberties groups.
"I don't support the idea of data retention at all but I do realise that there are ways that it can be more or less infringing on peoples'right to privacy,"Mr Wilson told Fairfax.
Senator Brandis'interview is reminiscent of an interview Mr Abbott gave in opposition when attempting todescribe the broadband policy he was trying to take to the 2010 election.
He said then he was"no Bill Gates"and"no tech head".
