Melbourne to Bali Direct - Are There Block out Dates?

I read in the forum that Air Asia x is releasing flights at 12.01am on 28th Oct 2014.
I have read these dates are between 26 Dec 2014 and 25th Oct 2015.

Does anyone know if there are block out periods/dates such as Australian school holidays June 28 through July 12
or Easter holidays etc.

Thanks
