The package in next week's state budget will include a $40.9 million boost to the Online Magistrates Court, including two new magistrates, Attorney-General Jaclyn Symes said.

The appointment of four County Court judges will also be brought forward ahead of pending retirements by existing judicial officers.

Ms Symes on Thursday said this meant extra judges would be available to deal with cases awaiting trial, after jury trials were suspended during Melbourne's second virus wave.

There will also be funding for two additional registrars.

The Victorian Civil and Administrative Tribunal will receive $56.7 million to deal with additional hearings virtually.

Meanwhile, $34.8 million has been allocated to help drive down wait times and $22.9 million to help courts manage caseloads.

Victoria Legal Aid, Victoria Police, the Office of Public Prosecutions, Corrections Victoria and services to support victims will share a $55.3 million budget boost.

"Courts and tribunals did a great job getting through the pandemic and they learnt a lot," Ms Symes said.

"Now they've told us what funding, resources and staff they need to drive down the resulting backlogs - and we have listened."

The Law Institute of Victoria has welcomed the spending, and said it hopes regional courts will also be included.

The Institute's President Tania Wolff said the money will help to prevent cases getting bogged down in the court system.

Also on Thursday, the government announced $11.7 million would be spent on expanding traceability systems for the state's agricultural products.

A recent pilot program on oranges grown in Mildura showed the fruit could be scanned anywhere along its global supply chain, and traced back to the farm where it was grown.

The "paddock-to-plate" tracing system is expected to boost exports and help authorities respond to biosecurity issues.

Meanwhile, the budget will also feature $5 million to fund the planting of 500,000 trees in Melbourne's west.

The trees will be planted in growth areas across six councils.

The government says in 2018, Melbourne's west had 5.5 per cent canopy cover, compared to 17.4 per cent in inner southeast and 25.9 per cent in the east of the city.
