They were deployed as part of a Victorian taskforce - comprising almost 25 Victoria State Emergency Service (VICSES) personnel - to support the state with the relief effort.

Most are volunteers, who are being accompanied by two support staff, to assist with the storm damage response, roof and chainsaw operations and other resourcing requirements.

The four volunteers from the Ballarat unit - Chris Bluett, Wiz Rennie, Trent Oldaker and Ben Lynch - travelled to Melbourne airport on Tuesday morning.

Speaking with The Courier en route to the airport, Mr Bluett said he expected the scenes to be "quite confronting" despite his decades of experience in the SES.

"We're expecting it to be fairly confronting. We've had some pretty bad storms in Ballarat but none of us have seen anything like what I've seen on the news [from WA]."

But he did not hesitate in putting up his hand to assist.

"All of us have done it for the same reason we joined SES in the first place - helping out the community," Mr Bluett said.

"They might be a while away but they are still part of Australia and are in need of assistance."

A volunteer of almost 40 years, he has been deployed to assist interstate with the clean-up after storms and floods but has never assisted after a cyclone.

It will also be a new experience for the other volunteers deployed from the Ballarat unit.

Volunteers required training and qualifications to either work safely at heights to repair roofs and use chainsaws, with the main tasks to be roof repairs and clearing trees.

"The main tasks will be temporary repairs to partially damaged roofs and clearing the fallen trees off roads, and trees that are preventing access to buildings and things like that," Mr Bluett said.

The taskforce was flown to Perth on two separate flights before and travelling to Geraldton by car, though Mr Bluett was unsure within exactly which community they would assist.

The deployment will last for three days before they return home on Saturday.

The taskforce's deployment comes after the Western Australian government requested 'boots on the ground' support from Victoria and New South Wales on Monday.

Cyclone Seroja made landfall as a category three storm late on Sunday, bringing with it wind gusts of up to approximately 170-kilometres per hour.

The damage it caused has been devastating to affected communities - destroying homes and businesses and leaving residents without power.

Emergency Management Commissioner Andrew Crisp said the scale of the damage was "quite big".

"We expect a big job ahead for our teams heading over. We're preparing what we can do to help now, with a member already deployed last night to assist with a smooth transition of our members in WA," Commissioner Crisp said.

"I want to thank those who have volunteered and their employers who let them go at such short notice."

He said Victoria would do "whatever we can" to support communities in WA and would work with all relevant agencies to assist the recovery effort.

VICSES Chief Officer Operations, Tim Wiebusch, said he expected the commitment would be significant throughout the recovery phase, with members to assist with a wide range of storm response operations from roofing to chainsaw work.
