Advocates are warning that quarantine and self-isolation to prevent the spread of coronavirus are creating the perfect storm for a spike in family violence and child sexual abuse.

The stark warning from Domestic Violence NSW spokeswoman Renata Field comes as other jurisdictions around the world grapple with domestic violence rates as high as three times the normal rate during coronavirus lockdowns.

The Morrison government on Sunday announced it is giving more money to domestic violence support services with $150 million to boost programs already in place. This will include counselling, the 1800RESPECT domestic, family and sexual violence counselling service, and Mensline Australia.

"In China, reports of domestic violence [during the lockdown] tripled. There have also been similar reports from the USA, the UK and Europe," Ms Field said.
