And while we're watching Channel Seven, here's another story that caught our eye, a discussion on Sunrise the other day about the Kardashians.

Yes really.

And whether they were breaking American law by plugging products on Instagram without telling followers their posts were paid for.

But what made us sit up was when the spotlight swung back to Australia.

DAVID KOCH: I reckon they disguise it really well, a lot of people. NATALIE BARR: Not that one probably, but the other things they probably do disguise. DAVID KOCH: Other things. Like, local people, in Australia. EDWINA BARTHOLOMEW: I think most people who follow the Kardashians would be aware that they have sponsorship arrangements, and if they're deleting all the ones that don't ... NATALIE BARR: There won't be much left! SAMANTHA ARMYTAGE: If they're holding something like this it's generally an ad. You don't normally ... NATALIE BARR: Yeah but they don't always do that, you know, a lot of people go to places and have free trips and ... DAVID KOCH: So many non-Kardashians do it SAMANTHA ARMYTAGE: What do you think of this, Beretts? MARK BERETTA: I think it should be all pulled back a bit actually, just relax everyone, it's alright. — Channel Seven, Sunrise, 25 August, 2016

So why all the laughter we wondered?

And why was Mark Beretta looking so embarrassed?

Well, a quick look at his Instagram suggested a possible answer.

Because in among the standard selfies we found no less than 11 enthusiastic mentions of Canberra's Jamala Wildlife Lodge, which costs non-celebrities around $1000 a night.

Obviously Mark loved it.

As do some other TV news and current affairs hosts like Studio Ten's Jessica Rowe, who's posted several snaps of the wildlife lodge to her Instagram account, including a few with her Nine newsreader husband Peter Overton.

And morning TV legend Kerri-Anne Kennerley also tells her Instagram followers about Jamala.

So, are they paid to do this? No they're not. But as Jamala told Media Watch:

Staying here is payment enough. They either get a discount or a free stay, which is worked out on their social media reach and how much coverage the celebrity would give us. — Sally Bradley, Retail and Information Manager, Jamala Wildlife Lodge, 7 September, 2016

Nice work if you can get it. Although Seven did tell us that Mark Beretta paid the 'quoted rate' whatever that means.

But it's not just Jamala that likes dealing with newsreaders and reporters.

Because, as Charles Morgan from marketing company Hello Social told us:

When you're using a newscaster they have more of an authority. You ... trust them and their posts from day one. — Charles Morgan, Head of Strategy, Hello Social, 31 August, 2016

Or as Instagram marketer Max Matthews put it:

They already have a high level of trust, so it's a safe bet by getting them to post, you're likely to see a return. — Maximillian Matthews, Social Media Marketing expert, 1 September, 2016

In other words, newsreaders can be trusted to promote stuff on Instagram better than almost anyone.

And that's making them a busy bunch, with Ten's Sandra Sully and Natarsha Belling and Nine's Davina Smith and Erin Molan among the ones who do it.

Another is Nine News's Airlie Walsh, who last year enthused about Contiki to her 15900 Instagram followers, posting 25 European travel snaps with the company hashtag before signing off:

I want to say a huge thank you to @Contiki for having me ... What an experience ... Thank you for an incredible time team! Xxx — Instagram, Airlie Walsh, 26 May, 2015

Cars are also popular with news presenter. And it's not hard to see why.

I mean who could say no to the loan of a souped-up Mercedes? Clearly, not Mark Beretta.

Road tripping! The AMG GTS and I decided to drop in on Bells Beach! — Instagram, Mark Baretta, 29 January, 2016

Or indeed to a top-of-the-range 4WD with room for the family, as loaned to Channel Seven's Morning Show presenter Kylie Gillies.

Look out ladies I am officially "Queen of the Pick-ups" ... Thanks for the loan INFINTI cars. — Instagram, Kylie Gillies, 5 August, 2015

Or to a flash new Audi for Sydney's Ten News host Sandra Sully.

Yep... Loving this!! — Instagram, shortblack_(Sandra Sully), 26 February, 2016

Or even a Jeep, which Nine's Weekend Today presenter Deborah Knight was proudly promoting not long ago when she was an ambassador for the brand.

A sure sign it's going to rain! @jeepaustralia — Instagram, Deborah Knight, 29 October, 2014

In fact Deb Knight appears to be one of the busiest posters, with her Instagram account praising a range of products, such as:

KarenGee clothing

HelloFresh food.

Assorted baby stuff from various suppliers.

And expensive cosmetics.

A very special delivery to get me sorted ahead of winter. The best skincare! @drspillerskincare ... — Instagram, Deborah Knight, 23 March, 2016

Also on Dr Spiller's distribution list are Ten News's Natarsha Belling and Sandra Sully.

And as the company told us it seems they're getting the merchandise-at up to $200 a jar-for free.

We have PR send them products, It's totally unpaid, but we do free facials and products for them and get a response pretty soon after on Instagram. — Sue Dann, Training Manager, Dr Spiller, 1 September, 2016

So is there anything wrong with this festival of freebies?

Well, none of them are Chinese. So that's a relief. And often the goodies are only lent.

But sometimes the companies that newsreaders are plugging make news for the wrong reasons. And that must be tricky.

Like when an Australian backpacker died in Rome on a Contiki tour.

Or when Audi's owner Volkwagen was discovered to have lied and cheated on emissions tests.

And who could ever forget the troubles at Jeep, which was anything but a reliable car?

But even without these potential conflicts of interest, is it a good look for journalists to be selling their reputation for a free set of wheels of a few pots of skin cream?

And shouldn't there be some rules, we asked?

The TV networks obviously think not, since they failed to respond to that question.

But Britain's Channel 4 does have guidelines, which we think should be adopted here. These require all on-air talent to tell the public what the deal is.

So that, if they promote a product or service:

... in exchange for free or discounted gifts or cash or any other benefit in kind they must ensure that they are fully transparent about the nature of the relationship with the product or service. — Channel 4 UK, Social Media Guidelines

In other words, are you being paid? Did you get it for free? How long will you have it for? And what if anything are you expected to do in exchange?

That's what the TV celebrities we've outed are failing to tell us. And they may well have no deal with these products at all. But the public has a right to know.
