I have done some ringing around today, and found these prices

Hawkesbury Race club which is where Gaddy & Annie, and R and I stayed last year is $155/night $14 breakfast, has undercover parking, and you need to supply own bucket, and carwashing stuff etc.

Or coach house inn a B&B (has enough room for 12 people) which is near the RAAF base, very close also, has a lockable place for vans, no undercover parking, but somewhere to wash them
$100/night incl breaky, shared bathroom this is a twin share.
$85 single person breaky included shared bathroom
$120 for double room with Ensuite
$110 for one person with Ensuite all incl breaky Only two rooms have Ensuites, and Sean and Jody Absinth will need one with an ensuite for Leela, and I would like an Ensuite

Let me know which you would like in the next couple of days and I will book, they will become less easy to get as time goes on as the AHD draws nearer, and if I book now, and if you all decide on the Hawkesbury we can be near each other, the Coach house inn we will all be together anyway as much smaller
