Props Logan Bayliss Brow and Leivaha Pulu are also training with the NRL squad.We mustn't be far off our top 30 now. I've got 4 spots left between these guys, but there are probably more I'm unaware of.
Riki (he's featured heavily on the Broncos website lately, wouldn't be surprised if he's already been upgraded to top 30)
Bullemor (had a development contract for 2021 according to nrl.com, but may have been upgraded, listed on Broncos website)
Kennar (listed on Broncos website)
Hetherington (listed on Broncos website)
Piakura
Kelly (not sure if he's returned after being sent to Souths Logan)
Luke (is he still training with us?)
Isaiah Tass (on a new development contract, doubt he'd be upgraded to top squad so soon)
EDIT: Forgot to add Callum Gahan, Brendan Frei and Ben Nakubuwai who Big Pete mentioned had been spotted training this pre-season
