Prepare the barbecue for direct cooking over high heat (230°C to 290°C).
In a small jug, combine the tomato sauce, Worcestershire sauce and Tabasco sauce.
Barbecue your bacon over direct high heat, with the lid closed for 1 to 2 minutes per side.
Once the bacon has cooked, remove it from the barbecue and cut into thin slices.
Spoon the sauce mixture onto the oysters. Top the oysters with the cooked bacon.
Arrange the oysters on the grill and cook over direct high heat, with the lid closed for 2 to 3 minutes.
