"I have been kicked in the face and punched and jostled. Again, not every weekend. But in my career I have been both kicked and punched in the line of duty.
"It is interesting, often if the people are still around when they sober up they are apologetic ... and they claim lack of memory. It is just when you put yourself into a situation where you are not in control of your actions."
Dr Bonning said he realised the Government was wary of any measure that could be labelled "nanny state", but more needed to be done - including bringing back bar closing times closer to midnight, or introducing "lock out" laws, where no new patrons are allowed in after a certain time.
In NSW, two deaths from so-called "coward punches" in 2012 and 2013 led to new 1.30am lockouts and 3am last drinks laws across the Sydney CBD entertainment precinct.
The controversial measures have resulted in a decline in assaults, including a 40 per cent decline in assaults in Kings Cross since the lockout laws and a 20 per cent decline in the Sydney CBD.
Business owners have criticised the laws as going too far, driving revellers away from the once-famed nightclub area.
Dr Bonning said he was not advocating a return to the "6 o'clock swill".
"I'm just saying bring it back towards midnight. And also stopping the incredibly cheap alcohol being available on corner stores."
