Try this:

=IF(ROWS($1:1)<=COUNTA(A1:A20),INDEX(A1:A20,SMALL( IF(A1:A20<"",ROW(A1:A20)-MIN(ROW(A1:A20))+1),ROWS($1:1))),"")

This is a CSE function (Ctrl + Shift + Enter)

Is there a function/formula I can put into a series of cells which can look
at a list (with repeat entries) and simply return the unique one.

E.g.

Tomato
Tomato
Banana
Tomato
Pear
Banana
Apple
Pear
Apple
Tomato

Would be displayed as

Tomato
Banana
Pear
Apple

Then I can use Validation on this 'filtered' selection to create a drop down
selection box.
