DFES information can also be pretty dated. I was nearby the John Forrest National Park fire the weekend before last and I was getting accurate updates via a local Facebook group well before it was even mentioned on the DFES website. The information might not always be accurate but in these instances no information is worse.Whenever there is a bushfire I want to know about over here I just listen to ABC. They broadcast the official info from FESA (which is fastidiously checked for fear or legal action) at regular intervals.
Before it was mentioned on the DFES website, residents were being warned, a number of appliances were deployed and numerous bombers were making runs dropping water (when they would have otherwise been in Parky/Stoneville). The fire was quite significant.
Perhaps the delays come from the time to assess the situation and the vetting process.
