Yes walking should be allowed. I am not convinced bikes are okay on the beach. You know when a pack of bikes starts racing it can get pretty hairy out there!
The beach "reserve" is plotted on private property. The underlying title belongs to the land owner but he is required to leave the land undeveloped to allow folks to walk along the coast line. The beach reserve doesn't belong to the government or the Queen.
So again I say, Where are these laws written down?
I'm accusing you of just making this up, don't you want to prove me wrong?
I say No Private Beaches and No Private Piers, no such thing.
Who are these experts and where are their opinions?
I don't see any thing in here:
