This from booking.com this morning

Good Morning,

First, let me thank you for your trust in Booking.com and the business we do together. We appreciate our partnership and what you do for our mutual guests every single day.

I would like to personally inform you of the outcome of a recent agreement reached between the Australian Competition and Consumer Authority ("ACCC") and Booking.com, whereas Booking.com has agreed to extend the commitments it has rolled out in the European Union to all accommodations in Australia (the "Undertaking").

Please accept this email as an introduction to the Undertaking as well as confirmation and assurance of how we intend to continue to do business together going forward. You will also receive official notification and further detail via mail in the coming weeks.

Here is a summary outlining the changes relevant to you pursuant to the Undertaking;

1. You may set different room rates and offer different conditions and availability on different Online Travel Agents - This means you don’t have to offer the same room rates, conditions and availability on Booking.com as other OTAs. This gives you greater flexibility to manage your offering across distribution channels.

2. You may offer lower rates or better conditions through offline channels (such as telephone bookings and walk-ins) provided you do not publish or market offline rates online - We have had feedback that our partners want the ability to discount through offline reservation channels without having to give us the same or better rates. From now on, we will not require the same or better rates in respect of rooms sold via offline channels, provided that you do not market those offline rates online (e.g. on your website or on meta-search sites).

3. There is no restriction on the unpublished room rates or conditions you may offer, provided you do not market those rates online - We understand it may be important for you to offer special rates to your loyal customers through non-public channels (such as closed-user groups) or to negotiate special rates on a bilateral basis (e.g. a special private group discount). Through the Undertaking we have clarified this position.

4. Parity with your own direct online channels and some availability - Going forward under the amended provisions, you are still contracted to give Booking.com parity in respect of room rates and conditions offered on your own website (which includes meta-search sites such as Trivago, Kayak, TripAdvisor or Google Hotel Finder when they redirect the consumer to your own website for booking). As set out above, we no longer require you to give us the same availability as our competitors, but in order to give meaning to our relationship, we require at least some availability in respect of all rooms and room-rate types.

No specific action is required from you. Should you have any questions about this letter, please do not hesitate to reach out to us via the Inbox section of your extranet. Thank you for your continued support and partnership.

So much for the competition watchdog, we will be putting up a sign in our reception to alert customers that they are paying 12% extra to book with this mob , as opposed to booking direct with us over the phone.
I would suggest that booking.com will start going through all websites now to compare rates and taking down those that don`t comply.
It may not make much difference to the current bookings but if enough motels do something similar or have something like this added to there website the word will get around.

Any thoughts on this and suggestions how to combat it ?
