@Robert Gentel,
I've finally found an explanation for all this.
Or a possible one.
It was, apparently, widely believed that the Rudd government would quietly dispense with Howard's proposed legislation.
It hasn't.
Here is one explanation...
(The other ones include that Rudd is a christian and personally favours it....or that key Aboriginal people are lobbying for it because of the increased violence, rape and child sexual abuse many Aboriginal people believe is due to internet porn in remote communities...but anyway..)
The ruling Labor party does NOT hold the balance of power in the Upper House.
There is a key christian right independent who can have a major effect on whether Labor legislation gets through or not.
He likes the internet filter bill.
I just read that quickly and I need to follow up....
