Dig with a Macleod tool, straight jets of water into the ground to penetrate, sprays on turned soil to cool. Rinse and repeat.
A thermal imaging camera can be handy to find the hot spots. Especially if you can get on the fireground overnight.
Mainly, though, you just need to watch peaty areas carefully until you’re sure they’re done and dusted. Regular patrols, especially ahead of a bad weather change.
Australian peat is very different to Canadian peat, though. Canada is wetter and colder, making this kind of overwintering possible. Here peat fires can smoulder for up to a few weeks, but they’ll either blow back up once it gets dry enough or go out once it rains enough. We never get that protective snow layer that keeps the fire dry but cool for months on end.
I haven’t been over but a couple of mates went last year. The part of Canada they were working has a deep peat/duff layer above permafrost. All the trees are rooted only in the duff so when the fire rolls through, it burns out all the root balls and suddenly every tree is a widowmaker.
Also Canada has reliable flowing water from snowmelt, so their tactics are focused on high pressure pumps and multi-km hose lays. Totally alien to the dry firefighting tactics we use in remote area work here in Aus.
