The beach between tidal limits is crown property usually the foreshore above that is owned by somebody, they may or may not tolerate trespassers and if it is a security sensitive site you may get arrested.
Otherwise property is subject to the trespass laws, the owner can deny access and he does not have to be reasonable. The aviators that trespass most are balloonists who land practically every flight without permission, usually a token landing fee is offered ( a bottle or free flight). As many balloons are commercial operations landowners may ask for more than a token payment, in practice a landowner cannot stop you gaining access, but there are some that will impound your aircraft and ruin your day.
