Sexual assault in NSW has increased nearly ten per cent while crime across most of the state has remained stable or fallen in the past two years.
The quarterly report up to June 2020 was released by the NSW Bureau of Crime Statistics and Research on Wednesday.
Sexual assault rose by 9.4 per cent year-on-year to June 2020 and a similar upward trend was reported in the previous quarterly report.
Four offences have trended down over the last two years: robbery without a weapon (down 12.6 per cent), steal from motor vehicle (down 12.1 per cent), steal from person (down 25.4 per cent) and malicious damage to property (down 5.4 per cent).
Crime patterns were significantly interrupted in April by the pandemic response and that's reflected in considerably fewer break-ins, car theft and retail theft, compared to the same period last year.
In the greater Sydney area sexual assault increased in Blacktown (up 24.4 per cent) and Sutherland (up 59.2 per cent).
The only other major crime with a significant upward trend in the Sydney was domestic assault.
Two Sydney regions recorded a significant increase in domestic assault in the past two years: Baulkham Hills and Hawkesbury (up 32.7 per cent) and Parramatta (up 9.9 per cent).
In the Hunter Valley, excluding Newcastle, there were nearly 20 per cent more sexual assaults.
In the Illawarra sexual assaults increased by 33.7 per cent.
Sexual assaults in the Southern Highlands and Shoalhaven skyrocketed with an increase of 63.9 per cent.
Domestic violence assaults increased in the Murray by 25.1 per cent.
BOCSAR Executive Director Jackie Fitzgerald, said the continuing increase in reported sexual assaults was a worrying trend.
"It appears that at least some of the increase in sexual assault is related to an increase in secondary and mandatory reporting of child sexual assault. We will continue to closely monitor trends in this offence."
