A lot of papers around the country use those WA Tabform assessments in Friday's paper. Some papers do have their own prices for their local meetings though. Some of them then have changed markets in Saturday's papers, I guess as you said reflecting movements in betting. But plenty of papers do stick with exactly the same odds in Friday and Saturday papers. If you have a paper that has different markets, I would go with the Friday one. It will often tend to produce better value.
