And Greens Senator Scott Ludlam has had a bit of a win in the Senate.
He has gained Senate support to order the government to produce/ table documents that outline the definition of metadata.
This comes after the Coalition circulated a consultation paper to the telco industry last week, clarifying what sorts of customer web and phone metadata the government wants Telstra, Optus, iiNet et al to store for up to two years.
The paper has been published today by Fairfax Media.
As Ben Grubb reports, the paper rules out the retention of destination IP addresses and URLs customers access online. But it does not rule out access to this detail without a warrant if a telco happens to store it anyway, outside the proposal's requirements.
It is also "murky" about what is required to be retained when it comes to internet metadata.
Over in the Senate, Ludlam - with the backing of Labor, PUP, David Leyonhjelm and Nick Xenophon - has ordered the government to provide a definition of metadata to be retained under the proposed data retention scheme and the paper sent to the telco last week.
Attorney-General George Brandis is required to deliver this to the Senate no later than 12pm on September 3.
