Yes, blue berry flax-lily is rated fire resistant, though that does not mean it cannot burn.
All four sources support that conclusion, but they describe it in different ways. Australian Plants Society Victoria’s field trials place Dianella tasmanica in the fire-retardant class: it resists the first flame wave but may burn once dried out. The ACT Government’s plant selector also marks the species “Fire Retardant: Yes.” These findings support its use without claiming that it will remain unburned during prolonged exposure.
The other assessments point in the same direction. The Sun City Texas Firewise Group rates flax lily low for flammability hazard, which it defines as the ease with which a plant burns at high temperatures for a prolonged period. Ozbreed placed five Dianella tasmanica cultivars, including Blaze, Tasred, Wyeena, Destiny and Emerald Arch, on its second list because the genus and species appear regularly on multiple fire-retardant plant lists.
Blue berry flax-lily is a shrub in the Asphodelaceae family. The consistent ratings make it a reasonable lower-flammability choice, but the field-trial wording supplies the necessary limit: once the plant has dried, it may still burn. “Fire resistant” therefore means better able to resist initial flame exposure, not fireproof.

How to read this page
The status above is computed from the cited rows below: independent recommendations can support a fire-resistant result, an avoid row can produce keep-away, and disagreement stays visible as conflict. Placement notes preserve each source’s own scheme rather than translating unlike rules into one scale. This is evidence about a plant, not permission to plant it in every part of the defensible space; Zone 0 remains noncombustible.
Where its sources say to plant it
Placement rules below use each source's own distances or named zones, tied to its rating.
They are not interchangeable with the directory's current Zone 0 guidance.

The evidence
Grouped by what each source concluded. Primary evidence rated the plant itself
(a lab, field program, or original curation); corroboration compiled or
republished another source's rating and resolves to its root lineage.
The table rates Flax Lily — Dianella tasmanica low for flammability hazard, defined as the ease a plant can burn at high temperatures for a prolonged time.
