Be very careful at this time of year near any of the beaches, good chance of being very soft with washed out entries/exits etc
If you stick to the inland tracks you will be good, dont be afraid to really drop your tyre pressures eg 10-12psi
Erringtons beach will be the big concern. This time of the the entry from Nora Corina end is usually washed out and you may need to go to the next entrance to access the inland track.
A sand flag is also advisable , along with a set of maxx traxx.
