The Sharks have thrashed the Broncos 31-4, producing the highest team score of the day thanks to try-scoring doubles from Blake Ayshford, Jack Bird and Sami Sauiluma.
Cronulla raced out of the blocks through Ayshford, who crashed over out to the left one minute in, with Valentine Holmes producing a rare sideline conversion.
Ayshford raced away for his second two minutes later, with a fine solo effort from 30 metres out creating enough room for him to run around under the posts for a bonus point try and far easier conversion for Holmes.
The next try came from the opposite flank when Sami Sauiluma made the Broncos pay for a simple knock on. It got even more ugly for the boys from Brisbane when Jack Bird also went over on the right wing for his first try as a Shark, making it 21-0.
An impressive run from Sosaia Feki put the Sharks on the attack again in the second half before Sauiluma showed good pace down the wing to earn his second of the match, improving the position enough to earn a successful conversion and a 23-0 lead.
That right edge continued to give the Broncos nightmares when Bird crossed for his second shortly after.
The match was long gone at 31-0 for the Broncos but Aaron Whitchurch at least saved his team the embarrassment of being held to nil when he scored a late consolation try to make it 31-4.
The result leaves the Sharks with the strongest attacking and defensive records of all teams at the Nines after two matches, a fact that doesn't surprise back-rower Chris Heighington.
"I'm not really surprised, we came over here to go well and win games. We have some really talented young kids and older heads, everyone is standing up and it's going good," Heighington said.
"The Broncos were young so we knew if they had to make a heap more tackles than us we would win the game."
