The two men are yet to be charged while police said it was too early to comment on whether the incident was terrorism related, they have said they believe it was a deliberate act.
“We believe based on what we have seen that it is a deliberate act," Commander Russell Barrett told reporters.
"The motivations are unknown, it is still the early days of the investigation."
Police have confirmed the two men are aged 19 and 24.
The incident comes just 11 months after six people were killed in a similar incident in nearby Bourke St.
Among those rushed to hospital is a pre-school aged child suffering serious head injuries.

Witness Jim said the 4WD was travelling west along Flinders Street at up to 100km/h.
"The intersection was full of pedestrians and he just ploughed through," he told ABC TV.
"The only thing that slowed him down was him hitting pedestrians."
