Jok not sure which one you looked at but i just looked at the one at nambucca heads and the powered site is $34 plus $6 per child per night so if you had two adults anad two kids per night that would be $46 a night. And has in the current high season. So if your going in March its low season so it will be only $23 per night plus children so rather cheap if you ask me!!
If you have the membership as well you get 10% off or up to $30 off each stay at any big 4 park.
the above price was at http://www.nambuccabeach.com.au/rates.asp
not saying your not right JOK but when you said that price i was shocked cause i have never ever paid that much at a big4 park. Yes they may be busy parks but at the same time they are maintained to a high standard and as a member if you rock up and check in and arent at all happy they will fully refund you your money and you can find somewhere else to stay if you wanted too. They are also very feriendly family parks which is why we use them as we take our four kids away with us and always find lots of other familys in the parks. I would rather have my kids stay at a park where there are lots of other kids then say a park that would have perm residents or lots of older visitors.
Anyway id love to know what park it was that you called and got that price from cause i will be avoiding them if that is how high there rates are!!!!
