Sourcing Good Light Roast Beans

I recently bought Average Joe’s Light Roast coffee beans that claim to taste like Neapolitan ice cream. They smell and taste sweet, but they’re $39 for a 1kg bag (regularly $49), plus $9.95 shipping.

Are there higher-rated light roast beans available in Melbourne or that can be shipped interstate? I’m new to light roasts and want a good one for cold brews and occasional espresso.
