Walker registration for the Du Cane range

Hi,
Myself and 2 other walkers were planning on doing a traverse of the du cane range in late September. We have registrations for the 25th for the overland track starting from lake st clair. I just wanted to double check if anyone knows if this is necessary or I should cancel the registration as we will not be walking the overland track itself. One more question I had was one of the walkers might have to postpone our start date to the 26th. Will this present much issue if we are booked for the 25th, or will we be fine to start a day late (assuming the weather is fine)? I can't seem to find much information on the parks website. This is our first attempt of the du cane range however we are all very experienced walkers and navigators, and I just wanted to double check we were following registration rules to be fair to other walkers.
Thank you!
