"NRL star" is somewhat of an overstatement. He may have been signed to Cronulla but from what I can recall, he's mainly played NSW rugby over the past two seasons, with very little NRL game time. Vast difference in quality between the two leagues, as there is between SL and the Championship.

Try Googling Newtown Jets and look at their recent match reports.

I am not sure that I would describe his performance as sharp - he was the least impressive of the backs IMO

You could certainly see what Tonga had to offer on Sunday, but clearly short of game time.

Another game against a Champ team (no disrespect) will do him no harm

He's played 3 nrl games in two seasons two of them off the bench......that's how good he is and why he has signed for Leigh!

More than Jarryd Hayne then.

...and indeed, unfortunately, more than The Plane is destined to play whilst sporting the cherry and white hoops. Regarding Brown, the YouTube collage I've seen struck me as positive: a couple of excitingly evasive carry outs from full back ( though the chasers looked a little raggle-taggle) and a dead halt tackle on a opposition FB, from what appeared to be right wing or centre, to thwart any hopes of said foe emulating his (Brown's) previous antics. Let's wait and see. If the proof of the pudding is in the eating, he needs to prove to be a pudding before the enthused amongst us, seemingly including DB, eat umble pie (or pudding... Need to work on this sentence).
