The following 30sec promo seems new(ish), I think? It is a combination of the previous 15sec iconic moments promo and roughly the last 15sec of the full Mel control room promo.
Also, curious about the frequency of BB promotion, I recorded Channel 10 in Adelaide between 4:30 and 7:30 and noted promos at the following times*
- 4:41 pm: 15sec iconic moments promo (already capped, although cap is missing launch date).
- 4:55 pm: 30sec promo with Mel (60sec version already capped).
- 5:19 pm: 30sec promo with Mel VO (shared above, at the start of my post).
- 6:18 pm: 30sec Mel promo again
- 6:35 pm: 15sec iconic moments promo again
- 6:50 pm: 15sec iconic moments promo yet again
- 7:21 pm: 15sec iconic moments promo for a fourth time - any guesses that this is 10's favourite version for this evening

* A chance I may have missed some while scrubbing through the various ad breaks - who'd have thought of skipping the programming to only watch the ads!?!

I’ve had Ten playing via their website (Melbourne based) since about 11:30am right through to 8:30pm, in an attempt to catch new or uncapped promos too (the things we BB fans do…

). The merged promo you’ve posted isn’t actually new, it hadn’t been uploaded but has been airing for about a week and a half (around the time the launch date was announced).
I gotta say, Ten are known for frequently playing the promo of their next big show (nearly
too much) and today the 1min main Mel promo played
at least 20 times over the course of the 11 hours I had it on… I’m almost sick of it now, haha… and that 30sec IconicMoments/BolderBadder promo aired almost just as much, if not more! If you want a gage, one or the other played in either every single - or at least every second - ad break over the course of today.
It’s kind of a shame because we know they have a whole bunch of other promos produced, most of which actually hint at twists or things to get excited about. But perhaps they’re gatekeeping those to air more often once the HMs go into lockdown?
In addition to the above, the “OG That Inspired” promo also started airing again quite frequently here this evening (maybe an additional 8 times?) and the 10sec “Returning Home Where It Belongs” bumper aired only once. So BB (and The Celebrity Traitors UK) well and truly dominated the Ten TV live stream promos in Melbourne.
…and yet, outside of all that, still haven’t caught the “rarer” and shorter promos we’re missing to be capped.
