I'm really pleased now that I thought to mention the advertisements, and I thank you Curious for posting those links.

I don't know where you live Linnie, but why don't you contact the Australian TS Society and ask them about the ads? I'm in Launceston so you can tell them that they're being aired here. They're probably running in Hobart as well, as we usually get the same ads unless it's advertising about local businesses or events.

I was going to suggest contacting your TV networks, but they can only show what they've been directed to show.

Good luck!
