Starting configuration for Australia
Boomerangs can move like rooks, or in a U-shape.
To move in a U-shape, move a boomerang as far as it can go in one horizontal or vertical direction without capturing, then make a left or right turn and move the boomerang in that horizontal or vertical direction without capturing, and finally make the same turn again and move the boomerang as far as it can move, capturing a piece if possible.
You cannot make rook moves two turns in a row.
