NSW will get its toughest gun laws ever under proposed changes to licence regulations.

A confidential list of proposed changes obtained by The Daily Telegraph shows the government is planning to tighten rules for buying and using a gun in NSW in response to a spate of drive-by shootings in Sydney's west.

The draft changes, prepared by the Ministry of Police and Emergency Services, include a rule that people who have been convicted of any violent offence, any sexual offence or those on good behaviour bonds will be banned from obtaining a gun licence.

Businesses applying for a gun licence will need to disclose all close associates, security companies will need to record each time a firearm is used and shooting ranges will have to report every injury on their premises to the NSW Police Firearms Registry.

Following high-profile cases, such as that of Shamin Fernando, all unlicensed shooters at gun ranges have to declare whether they have ever suffered from a mental illness each time they visit.

Fernando killed her father in 2010 after she stole a gun from Sydney Pistol Club.

She suffered from depression, schizophrenia and psychosis, and her family have been lobbying the government to make gun laws stricter. 

Other changes considered include forcing applicants to prove they can comply with regulations to store their firearms safely.

The government will also consider banning shooting fish. The government has to review existing legislation and update it by September.
