Hey Tomnewcombe,
Here is a hint, let your tyres down to around 15psi to get through the loose sand on the beach and take a shovel and snatch strap just in case. Problem with finding the soft stuff is that you have to drive through it to find it, hope you bought an Automatic.
The inland track is very bumpy and takes ages but is easy to get through.
No too much at Wedge apart from some surf and some dunes so take what you need with you. Little to no shelter for girlfriends or partners if it's howling so leave them behind.
Good spot, best in a Westerly wind with Sou'West swell.
Have fun,
