Yes agree with NDL_Diver about taking a boat dive on day 1, worst case the DM will be your dive buddy. Also, in April 2019 Dive Friends did have a buddy board. It's the only one I've seen personally. Another option is to hang at the dive shop or at the resort's bar. Divers are a friendly bunch and it shouldn't take long to find potential buddies. Also, your first full day in Bonaire you will likely do your mandatory check dive at the resort. In my 2 recent experiences there were 10-20 people, mostly in pairs, that go to the lecture and then immediately head to the water for a check and dive. Good time to make some friends and worst case ask if you can go with an existing pair.
Also I did my AOW with Paul @ BonScuba in April 2019 and had a blast doing my 5 dives. Highly recommended as a private instructor and guide. Paul picks you up at your resort and takes you to selected spots. Simple, easy and safe. Might be a good way to start your Bonaire diving.
My Canadian 2 cents. Enjoy. Bonaire is a GREAT diving destination.
