Place the olive oil, lemon juice, salt, pepper, oregano, paprika and garlic powder in a large bowl and whisk to combine.
Add the prawns to the bowl and toss gently to coat evenly with the marinade.
Marinate for at least 15 minutes or up to 2 hours maximum.
Skewer 4-6 prawns on each soaked skewer or metal skewer and place on a plate while skewering the remaining prawns.
Turn on and heat your BeefEater® BBQ to a medium high heat and cook the prawns for 2-3 minutes on each side until the colour is pink and prawn is opaque.
Serve warm with fresh parsley, sprinkle of thyme and lemon slices and enjoy!
