Forming a carpet, with Dichondra repens in Melaleuca armillaris scrub killed by fire in early 2020. The flowers are very dwarfed and the photos make them look a bit 2 tone mauve, but they were very much white and purple. There were no typical V. banksii leaves (round with a sinus) to be found. All the leaves that look like that in the 3rd photo are actually Dichondra.

Is this just Viola hederacea? That species is extremely common here, at the moment there'd be 1000's of them flowering. But this one caught my eye due to its diminutive size, the whole flower being around 5mm across. It was also growing alone from forest litter, whereas Viola hederacea will typically form quite large colonies.
