UPDATE: PRIME Minister Julia Gillard has visited Victorian fire-affected towns of Seaton and Heyfield.

Ms Gillard was joined by Victorian Premier Ted Baillieu while visiting Seaton and Heyfield, where a bushfire destroyed more than 20 homes, and claimed the life of an 84-year-old man earlier this month.

The prime minister said she wanted to personally thank those who had fought the fire.

"I've also been here too to say to this community that we are thinking of them," Ms Gillard told reporters.

"It's important to note that this fire danger isn't over. We are yet to face what could be the worst of the bushfire season."

She urged Victorians to remain vigilant to the fire danger over coming weeks.
