Been trying to get a few days off before the 'big rush', so sorry I did not answer earlier. O.K. the nine are (excluding your own 'booking button':

Agoda - for Asian customers.
Book Easy - as this is our VIC's.
Booking.com - for obvious reasons.
Expedia - North American customers + not many operators on it.
Jetstar/Hooroo/Qantas - I'm closest motel to our airport.
QuickBeds - likely to get zapped as produces very little business.
RoamFree - also likely to get zapped as produces very little business.
The Hotel Network - gets us lots of Government (RMS) bookings.
Wotif - for obvious reasons.

Hope this helps
