Who’s the next Aussie pace express?

As an Indian cricket fan I’ve been amazed by the legendary trio of Josh Hazlewood, Pat Cummins and Mitchell Starc over the years, but let’s face it these guys are getting on a bit and are probably approaching the twilight of their careers. I don’t follow much of Australia’s domestic cricket scene so I’m curious who’s the next fiery quick ready to take the baton, any names emerging from the Shield or U19?
