A Mystery in Palma de Mallorca

An unusual souvenir in Palma

Can anyone solve this mystery for me? In Palma de Mallorca, in a souvenir shop, in amongst children's flamenco outfits, items made with shells and assorted ceramics painted with red coral designs, was this stand. 
   Australian Aboriginal boomerangs decorated with traditional dotted designs!!
   Why? We're a long way from Aussie in the Mediterranean!
   Why would a Spanish island have these for sale? Is there a link between the two countries I don't know about? 
   Or did the souvenir buyer for the store like the look of them, think,'Oh, we'll just paint Mallorca on them & put them out in the shop.'
  A mystery indeed. I'd love to know the answer.
