Tupou, aka the Tongan Thor, has been selected for the Wallabies European spring tour, but he can't play yet.
The former New Zealand schoolboy rugby star was one of four young players picked by the Wallabies as development players for their coming European spring tour.
The giant prop, now 20, rose to fame in 2014 for his running and try-scoring deeds with the Sacred Heart College first XV in Auckland.
Taniela Tupou is just 20 with only three cameo appearances for the Queensland Reds but the sky is the limit for the most dynamic young prop in the country.
Wallabies boss Michael Cheika may have another bolter up his sleeve on Tuesday with 19-year-old Queensland winger Izaia Perese also a big chance of a spot in the squad.
If the duo are taken on tour, their sole target would be the Australia A clash against the French Barbarians in Bordeaux on November 24, rather than any of the five Tests.
