Urgent cases relating to children caught up in parenting disputes will be rushed through the courts within 72 hours, as the Family Court and Federal Circuit Court report a rise in calls for help during the coronavirus crisis.

Key points: The courts will hear matters in a dedicated COVID-19 list

There has been a 39 per cent increase in urgent applications filed in the Family Court, and a 23 per cent increase in the Federal Circuit Court over the past month.

Cases set to be fast-tracked include disputes where there is an increased risk of family violence as a result of social restrictions put in place to curb the spread of COVID-19.

The two courts, which share responsibility for dealing with family law matters, will have a dedicated process to deal with cases needing immediate attention in place from the middle of next week.

Will Alstergren, Chief Justice of the Family Court and Chief Judge of the Federal Circuit Court, said court staff were "working tirelessly" to ensure Australian families were supported during the national emergency.

Coronavirus restrictions have added to the complexity of some parenting orders around the country, which set out the terms in which shared custody or supervised contact with children are managed.

The courts had received advice from women's legal services about an increase in the number of people coming to them for help during the emergency.

The closure of state borders has left some children unable to travel between the homes of their parents or guardians, and the courts may need to step in to organise other arrangements while such travel bans are in place.

"Applications that are eligible to be dealt with through the COVID-19 list, especially those involving issues of risk and family violence, will receive immediate attention and will be triaged by a dedicated registrar who will assess the needs of the case and allocate it to be heard by a judge within 72 hours of being assessed," Chief Justice Alstergren said in a statement.

"It is important that these urgent COVID-19 applications are closely managed on a national basis so that they can be heard as swiftly as possible given the unprecedented circumstances we are facing."

The courts may also have to step in when a parent or guardian, or the child themselves, have tested positive for coronavirus, and usual parenting orders cannot be followed.

Many parents working through changes without courts

Paul Doolan, chair of the Family Law Section of the Law Council of Australia, said the announcement would be welcomed by his colleagues, who had seen a rise in the number of new clients seeking urgent advice, along with existing clients needing further support.

Despite the increase in applications to the courts, Mr Doolan said many families that had parenting orders in place were trying to sort out their differences without the need for judges to get involved.

"I think a lot of people are trying their very best to be sensible and reasonable, and try and place alternate arrangements, if the existing ones are simply impracticable because of the health and safety concerns at the moment," he said.

"There are, undoubtedly, outlier cases where people are not acting reasonably, or they're using these circumstances as an opportunity to perhaps obtain what they see as a strategic advantage.

"Most people realise this is a situation which is once in a lifetime for — hopefully — all of us, and they're trying their best to make arrangements to put the best interests of their children first."

Mr Doolan argued the fact the new arrangements had been put in place showed the Family Court and Federal Circuit Courts were not properly funded, and hoped it would reignite debate about how the courts are resourced.

Some contact centres, where some parents are allowed to see their children under supervision, have also closed during the outbreak.

Making applications with the courts has also been simplified during the emergency, with paperwork lodged electronically and hearings held using videoconferencing.

The courts' dedicated COVID-19 list will run for at least three months.
