Grease slice tin (27 x 17cm) well and line base with baking paper, allowing the baking paper to overhang each side (to assist with removal once it's ready to slice).
Crush the biscuits until they resemble fine breadcrumbs using a rolling pin, chopper or food processor. Place in a mixing bowl.
Add first measure of coconut to the biscuit crumbs and butter, and stir to combine.
Press the biscuit mixture into the bottom of the slice tin and smooth with the back of a metal tablespoon. Place into fridge to chill.
Whisk the eggs and sugar in a mixing bowl until well combined. Whisk in sifted flour, rind and juice. Pour over the biscuit base.
Bake for 30 minutes. Toast the second measure of coconut in a frying pan while the slice is baking. Once baked, sprinkle with toasted coconut.
Allow to cool in slice tin. Once cool, remove slice from tin and cut into squares.
