Welcome to the Bunnings Workshop community. It's fantastic to have you join us, and thank you for sharing your question about resurfacing your driveway.
I suggest using Gripset Betta 1L Concrete Crack Filler to fill in the cracks of your driveway. However, if the cracks are too deep, I recommend using a Moroday 15mm x 5m White Gap Filler Rod to prevent the filler from sinking too deep into the crack. Before you apply the filler please note that the driveway must be thoroughly cleaned especially between the cracked area of the driveway.
