Support workers have also heard increased reports of stalking and monitoring by abusers in the ACT since the outbreak of coronavirus.

Victim Support ACT saw a 130 per cent increase in new family violence matters in June, compared to the same period last year.

Victims of Crime commissioner Heidi Yates said COVID-19 was causing people to take more direct and predictable routes from home to work, which abusers had capitalised on.

"People are feeling watched by abusers and reporting that in higher levels than they have in the past," Ms Yates said.

The service also reported a 50 per cent increase in sexual assault matters last month, when compared to 2019.

Ms Yates said applications for financial support with an "immediate need component" had tripled over the last three months.

"That's generally where people need assistance to relocate or improve the security for where they're living in terms of replacing locks on windows or security screens," she said.

"Of course people are trying to deal with all this while generally having less contact with natural support networks like friends and family and even co-workers if they're working from home.

"They're walking on eggshells in terms of the abusers' conduct but then having to hold things together throughout the day and night for school-aged children who they've been responsible for teaching and providing all the emotional support their kids might usually get from friends or teachers."

ACT Domestic Violence Crisis Centre deputy chief executive officer Dearne Weaver said recently they had also seen an escalation in the severity of the violence.

Ms Weaver said the support service had seen an increased level of high-end assault rather than the usual common-assault cases.

While domestic violence-specific statistics were not available for the period, ACT police reported 753 cases of assault from April to the end of June and 92 cases of sexual assault during that period.

This was compared to 740 reports of assault and 125 of sexual assault, on the same period last year.

Ms Weaver said the fact police had not seen a huge increase in crime should not suggest it wasn't occurring.

"Being isolated, being socially-restricted and not having access to your usual social networks and school and playgroup communities would all be a real recipe for someone being able to use those coercive controls in a relationship," she said.

"We know that when restrictions are in place it becomes more difficult for people to report violence because the person who is presenting risk to them is always present."

Ms Weaver said the crisis centre had experienced an increase in reports of mental health concerns and individuals at risk of suicide.

"There are barriers to people reaching out during those periods of isolation that we don't always have the answer to, but certainly we have email, we have text messages, we have online chat and I would encourage anyone in any way shape or form to make contact if they're needing support."
