I remember GTV trialled having their weekend bulletins read by someone standing up in 2008-09, rather than sitting down, though I can’t remember why it was introduced.
This appeared to cease once GTV got a new set in August 2009 (when they got a set exactly the same as what Sydney got, and what Brisbane would get a month or two later). However, I do remember the standing up format continuing intermittently only for major news headlines (or sometimes the first story of the bulletin) after that.
I remember when GTV implemented the 2006 graphics, the background (of the live Melbourne CBD) lasted only one year, then in 2007 they introduced a wooden desk and had the headlines blend into a static Melbourne background.
At that time, HSV introduced the twisted metal set with a live Melbourne background, so as to give it consistency with its Sydney counterpart (prior to then, the Morning and Afternoon News came out of ATN and HSV, respectively).
