The new head of the ACT Emergency Services Agency (ESA) says the Canberra community should be prepared for a significant bushfire season.

Dominic Lane today started his role as ESA Commissioner, after leaving his position as Assistant Commissioner with the New South Wales Rural Fire Service.

Mr Lane says the bushfire season will continue until there is significant rain in autumn.

He says, in the short term, firefighters can expect a couple of days of respite from the hot weather.

"The welcome rain of up to seven millimetres overnight was very welcome for firefighters in giving them some rest," he said.

"But of course we will see the weather warm up towards the end of the week.

"One can only hope that we won't see as bad a fire conditions as we saw on last Tuesday and again last Saturday.".

Mr Lane takes up the job just days before the 10th anniversary of the Canberra bushfires.

"It's an important event for Canberra and on a personal level, it's important that we learn and reflect on any emergency," he said.

"Whether that be the Victorian bushfires of 2009, the fires in NSW in 1994 or the Black Christmas fires."
