Did you notice if this fungus had pores? If so I can confirm this genus (Tylopilus ). This genus seems to be one of the early 'boletes' appearing this season. These are mycorrhizal, that is they are growing in association with nearby plant (usually trees) roots. Did you by any chance notice the trees that were growing nearby please? A nice looking fungus.
Sorry - I could not fit my phone down any further in the burrow to get a photo underneath. The only thing I can tell you, because I cannot ID plants or trees, are that the main trees growing around the area are casaurina and eucalypts.
